Incompatibility: item bestowal with inverter gates

[idarob]

Item bestowal using the force floor method seems to be implemented, but doesn't work when using an inverter gate that will switch the force floor direction upon start of the level. This works in CC2, but in LL the monster will move off the force floor leaving the item behind.

this does work now! — with a caveat. in lexy mode, an actor that starts on a force floor is currently free to move off of it on its first move. (this is a natural consequence of the cc2 rules + lexy mode running at 20 fps.) i should probably fix that, but in the meantime, it does at least work for monsters that take forced moves
