BUG FIX: Fixed a bug in the Dive Planner where under some circumstances an ascent leg would incorrectly labeled as a descent leg and given zero time duration. This would lead to incorrect gas usage calculations for this leg, as well as the run time being short by the time it would take for this ascent leg. Note that this affected the dive planner, and not the real-time decompression calculations. This fix is the only change for version 28.
