Add best mix function to planner cylinder model

Browse source 
This allows calculation and selection of best mix in the planner cylinder
entry, by entering the gas depth, followed by "b" for best (trimix) mix, or
"bn" for best nitrox mix.

The UI is not intuitive, but it is quick and easy.  At the very least, it
should be documented.
