CGameHandler::arrangeStacks: honour removableUnits of CGGarrison

Browse Source 
Now server properly check allowed actions for CGGarrison. Fix issue 2303
Server now allow all stack arrangement as long as troops stay inside garrison.
It's possible to put more troops inside using swap/merge/split, but not take anything out if it.
