Only use deco gas for calculation if option is enabled:
The gas menu meanwhile provides the possibility to select a gas for deco (having the gas switching reminder visible) without the need to visualize the reduced deco time. If the visualization of the deco considering all gas changes is wanted then this may be enabled by selecting the gas additionaly for deco calculation.
