Dev bugfix: Consider decogas in planner independen from calculation setting:
Some time ago the selection if a deco gas is used for live deco calculation or not was introduced. The planner did not consider the option as well causing it to ingnore deco gases in the planning what is not intended. To fix this the calculation flag is set at planer simulation start for all deco gases.
Beside this the cursor is now placed in the bottom line at "next" instead of the first menu item.
