ADD: Description for Acclimatized (Desert) skill, added by some modded campaigns

CNG: Immobilization attempts on Wheeled targets are now only -25 to hit, and on Half-Tracked targets -35 to hit; all other targets still -50 to hit
CNG: Penetrating hits on the player vehicle that don't knock it out can still cause spalling injuries to crew in the hit location
CNG: For guns where RoF is NA and there's one or more dedicated Loaders, there is now a penalty to hit if the Loader is / Loaders are not on Reload orders (player unit only)

FIX: Stock and captured Crusader III availability began too early (thanks Marsouin!)
FIX: Hull Loaders in Grant tanks can now no longer fire the turret smoke mortar; does not apply to units spawned before the update is applied (thanks Marsouin!)
FIX: 'Advanced Gyro Use' skill now properly replaces the basic version
FIX: Occasional crash after final campaign log is exported
FIX: Changed requirements for adding 'Coordination' skill, since previously 'Natural Leader' was a prerequisite but could be replaced by 'Inspiring Leader'
FIX: When a crewmen gained familiarly with a crew position, the previous level of the skill that it replaced was not removed
