Subject: Added the possibility to choose gases  in the planner.

Added the possibility to choose gases in the planner,
now the user should click on the name of the gas, a
popup window will appear, asking the user to choose
what gas he wants for that ascent / descent.

now we need to hook that up with the createDecoStops
method that calculates the decompression.
