Planner: Add backgas breaks
If the corresponding checkbox is checked the planner does interrupt pure O2 deco after 12min for 6min on cylinder 0. To make this work for air I removed the gasmix_is_null logic. I guess that makes the planner feature complete for the next release. [Dirk Hohndel: trivial merge into latest master] Signed-off-by: Robert C.
