With the current release candidate of Qt 5.6.0 we get into an infinite
recursion of the grid layout engine. This had happened before (prior to the 5.6
beta) and it appeared that setting the maximum width of the columns was
sufficient to fix this. But with the RC even that isn't sufficient, so now we
give up on having QML figure out the best possible column width and hard code
both preferred and maximum width to the same, predefined values. That's a total
shame, but at least now we can build against Qt 5.6 without infinite recursions
and crashes.

Lubomir found better compressibility data for the pure gases that we
need for scuba, making the air table superfluous: we get good values
from just regular linear mixing of the Oxygen, Nitrogen and Helium
calculations.
Also, rather than using a quintic polynomial, a cubic one does
sufficiently well, making for smaller code and fewer coefficients.
And judging by the reactions from people on G+ (as well as just looking
at how good the fit is with the air data), this is all the right way to
do this, and this thus removes the Redlich-Kwong equation.

This goes back to just doing air compressibility, but using the

As it turns out, the van der Waals equation gives results that are
numerically not really useful, so we use the Redlich Kwong equation
which is, according to Wikipedia, much more accurate, which can be confirmed
given the empirical values for air.
As opposed to the previous approach with a look-up table, this takes
into account the actual gasmix. This always assumes the gas to be at
20 degrees Centigrade.

"weights" and "cylinders" are QStringList Q_PROPERTIES, and Grantlee
should be able to render them, but it doesn't.
To be able to print the whole list of weights and cylinders we
introduce two new QString properties "weightList" and "cylinderList".
The variable replacement in the previous patch deals with the
conversation of the user side HTML, e.g.:
USER -> INTERNAL
"{{ dive.weights }} -> {{ dive.weightList }}"
"{{ dive.cylinders }} -> {{ dive.cylinderList }}"

The current Grantlee template loading scheme does not
allow a preprocessing layer. With the recent DiveObjectHelper
changes the layer is required if we don't want to add a set
of dummy methods and Q_PROPERTIES which will only inflate
the DiveObjectHelper class.
Use the already present helper readTemplate() to load the
raw HTML template and pass it to a static function which
does some variable replacement to accomudate DiveObjectHelper.
This change is done for the sake of not breaking the Grantlee
HTML variables on the user side!

Normally this is triggered when the DiveDetailsView component is
completed, but since QML isn't recreating this component unless we switch
to a dive a couple of spots in the dive list away from this one, we
wouldn't get any changes in the data reflected in the profile.
But since this now redraws the same dive that potentially was drawn last,
we need to make sure we call plotDive() with force=true.
I also suspect that this could help with the strange bug that sometimes we
show a blank profile after certain edits.

There was a reported case of an import of a dive that gave a salinity of
35g/l. This is an actual salinity (an amount of salt in the water) but
for subsurface the salinity is actually the density of the water. So for
too small values of the salinity add the density of fresh water.

This is questionable, but perhaps useful.
When showing imperial cylinder sizes, show both the nominal value (with
no compensation for compressibility of the gas) and the "actual" amount
of gas the cylinder contains.
So an AL80 will show as a size of "80 (77)cuft", because while 80 is the
nominal size, the actual amount of gas that will fit is just 77 cuft.

We had two totally different usage cases for "get_volume_string()": one
that did the obvious "show this volume as a string", and one that tried
to show a cylinder size.
The function used a magic third argument (the working pressure of the
cylinder) to distinguish between the two cases, but it still got it
wrong.
A metric cylinder doesn't necessarily have a working pressure at all,
and the size is a wet size in liters. We'd pass in zero as the working
pressure, and if the volume units were set to cubic feet, the logic in
"get_volume_string()" would happily convert the metric wet size into the
wet size in cubic feet.
But that's completely wrong. An imperial cylinder size simply isn't a
wet size. If you don't have a working pressure, you cannot convert the
cylinder size to cubic feet. End of story.
So instead of having "get_volume_string()" have magical behavior
depending on working pressure, and getting it wrong anyway, just make
get_volume_string do a pure volume conversion, and create a whole new
function for showing the size of a cylinder.
Now, if the cylinder doesn't have a working pressure, we just show the
metric size, even if the user had asked for cubic feet.

This actually didn't make a difference for the common case, since our
simplified gas compressibility model had a compressibility factor of 1.0
up to 200 bar, and increased smoothly from there. As a result, the
common 2400 and 3000 psi workpressures didn't really see an effect from
this.
Not taking compressibility into account does kind of make sense for
cylinder naming, since the cylinder may be used for different gases with
very different compressibility characteristics.

This marks "surface_volume_multiplier()" static in preparation for
changing it to use an actual honest-to-goodness compressibility
estimation. Without that, it wasn't obvious that the function wasn't
used in other random places.
Also, remove the "wet_volume()" function. It was unused, but more
importantly, it was wrong. Yes, it was the inverse of "gas_volume()",
but when you calculate wet volumes from the imperial sizes, you don't
actually use the "real" gas volume, you use the idealized one.

This allows the user to delete the currently shown dive. This action takes

Instead of re-calculating all the interpolation data for each plot entry
(which means that we have a quadratic algorithm that walks over all the
plot-info points for each plot-info point), we can just update it
incrementally within any particular interpolation segment.
The previous cleanups made the code sane enough to understand, and makes
it trivial to see how you don't have to recalculate the full thing.
This gets rid of the O(n**2) algorithm, and it instead becomes O(n*m)
where 'n' is the number of plot entries, and 'm' is the number of gas
segments (which is usually a much smaller numer, typically "1").

With the two bigger simplications, this just re-organizes the code to do
the "interpolate.pressure_time" update that is shared among all the
"after segment start" cases in just one place.
That leaves the get_pr_interpolate_data() much simpler, and makes it
much clearer what it actually does.
In particular, it becomes very obvious that "interpolate.pressure_time"
is constant for one particular segment (it's the total pressure time),
and that "interpolate.acc_pressure_time" is the one that gets updated
for every entry.
The next step is to only call this for the first entry, and then update
just the "acc_pressure_time" in the caller.

Getting rid of the pointless always-zero pressure now makes it obvious
how some of the remaining code can just be removed too: there is no
point in re-initializing the pressure_time entries to zero at the
segment start, because they started out zero and we just checked that we
don't do anything to them before we hit the segment start.
Similarly, now that the silly pressure testing is gone, it is obvious
that the code for "i < cur" and "i == curr" cases is identical, and the
two cases can just be collapsed.

In the function fill_missing_tank_pressures(), we only ever call
get_pr_interpolate_data() if "pressure" is zero. So passing it in as an
argument, and then testing whether it is zero or not, is just totally
pointless, and only obfuscates things.
This whole thing seems to be due to people editing the code over time,
with the tests becoming superfluous as the code around it changed, and
nobody looking at whether it actually made sense any more.
