magic mover ui feedback

okay, that was the most exciting testing i've had in a while. awesome feature!

a: the current ui makes it look as if it's possible to drag things from one lot to another directly (say, a basement to a lot that has none) without first putting it in the bank and restoring it after. it needs a red x if you try to drag from one lot to another and a message in chat if you actually try to drop it over the box.

b: the change house/change basement arrows that cycle through what you have available should see what homes/basements you have stored as well, or give a reminder to check the property manager as well.
