When an airplane was landed and ordered to another airstrip or service depot, the aproach distance was not properly calculated since it was not taken into effect that its current altitude is zero.

Delete mods/d2k/bits/turret1.aud (not mods/d2k/bits/TURRET1.aud). This old, unused file was causing oddities for users with NTFS since we had two different files in the repository with filenames that differ only by case, and NTFS has case-insensitive filenames.
Add mechanic
Added mobile gap generator. It is currently unbuildable and it does not generate shroud - this requires some additional shroud work since you can paint shroud across the map by moving it.
Much better yak management. Map improvements.
