Bugfix calculation of needed gas: Sometimes a gas was not calculated because of it's change depth calculation. Rootcause was a problem in the setup of the gas change list. The old function collecting milestones like time to first stop etc. has been removed because after the deco compression the complete profile is available. Instead of doing another way of profile calculation the existing profil is now evaluated and the time stamps / gas consumption derived from there.
