HOTKEY - Toggle Throw

[mbc]

Even though you can still throw grenades and beach balls by clicking on a tile, what about every other item? It might make things like using bowling balls or the butcher knife quite a bit easier, but they probably shouldn't be hard to use in the first place just because of the throw UI button.

Also, do we even have room for this hotkey? Home, End, Pgup and Pgdn are already taken.
