Hey,

First of all, thanks for the new MOVEITEM_IGNOREMOVABLE flag added to MoveObjectToLocation() function. This, however, arised a new lack of feature: there's yet no neat way to move item to (in) container if it's set unmovable.

Thus I wish you could add a new parameter to MoveItemToContainer() function, which would let us use this great flag and get rid of annoyance of making item movable before and again unmovable after the move.

Though not as much used (and I'm not sure if it's useful at all, but for the sake of completeness), support for this flag could also be added to MoveItemToSecureTradeWin().
