To make box-and-whiskers charts selectable (select corresponding
dives when clicking on box), save the dive list with the quartile
data.

If we want to make bar charts selectable (when clicking on a
bar select the dives the bar represents), then we must store
the dives behind bars. Therefore, use dive-based bins instead
of count based bins in bar charts and pie charts. This gave
some churn because every structure where a count is stored
has to be changed to store a vector of dives. Try to use
move semantics where possible to avoid duplication of dive
lists.
On a positive note, the count_dives() function of the
binners can now be removed, since it is unused.

The people binner (called "buddies") is too coarse. Split into
buddies, dive guide and people (the old "buddies", which is
a combination of buddies and dive guide).

Copy&paste error: the 20 m binner binned to 10 m.

When calculating the quartiles, we need the count of dives
anyway, which makes it trivial to export this value to
the frontend.
Fixes an erroneous "mean", which should be "median".

Trivially a copy of the "buddies" code.

The dive sites where sorted by location in RAM, which is just
silly. Add a DiveSiteWrapper that sorts by name, though that
should probably be improved.

This makes sense and is easy to implement.

This was requested on the mailing list and it makes sense to
have it. Of course, not all charts make sense: e.g. a plot dive-#
vs. count is a bit redundant...
Sadly, this can't use the generic IntRangeBinner, because dive-#s
start at 1, not 0.

This was requested on the mailing list. Reduce code size somewhat
by deriving the binner and the variable classes from common
base classes with a mean-vs-max flag.

The StatisticVariable class hierarchy encapsulates the concept
of a dive-variable, which can be plotted in charts either as
dependend or independend variable.
There are three types of these variables:
1) discrete: For example dive buddies or suit type.
2) continuous: Has a notion of linear metric - can be
used as histogram or scatter plot axis.
3) numeric: Like continuous, but allows for operations
such as calculating the mean or the sum over numerous
dives.
All variables support binning. The bins are defined per
variable.
Continuous variables can be converted into an arbitrary
double value, which is used to be plotted on a continuous
axis.
Moreover, numeric variables support a number of operations,
which depend on the variable.
Since binning is based on different types, the code is rather
template-heavy. Of course, this could be solved with
unions/variants and runtime-polymorphism, but using templates
was just much quicker. Notably, this uses the CRTP
(curiously recurring template pattern) where a subclass
passes itself as argument to the baseclass. This is a weird
kind of "reverse inheritance".
The StatsTranslations class is a dummy class which will
be used to collect all translations of the statistics
module.
This includes changes by Dirk to fix compilation of the
downloader.
