Add code to enter SAC rates for dive planning

This just provides the infrastructure to enter the data, nothing is
calculated, yet.

This adds a new get_thousandths() helper function so we can enter
information of the 'mili-' type as decimal values. So things like
"14.5 l/min" or "0.75 cuft/min" are parsed correctly and converted
into a ml value.

In the process of implementing that I also fixed a bug introduced in
commit ab7aecf16e96 ("Simplify dive planning code") which broke the
get_tenth() function.
