To-do before stable testing build (based on rev 372)

*Fix German barracks yardmap so leigs can exit.
*Fix Partisan shack yardmap so partisans are more reliable
*fix LoS bug on prone/standing up for sniper, scout, panzerfaust, commando

other?

*Fix water transports getting stuck on load/unload

Fixed all of this, and potentially some crashyness. More things to fix?
