Add Restrict OOB Placement Setting

[Spekio]

Enhancement: Please add an option to restrict placement of objects out of bounds of the room you are currently in. I find that I'm frequently finding misplace OOB objects. I'm guessing a lot of these are from trying to change rooms, but it happens much more often than I'd expect.

In addition it would be nice Lonn could help in some way with finding OOB objects that have been placed. The showing of OOB objects when clicking on a room definitely helps, but it can be hard to see the OOB entities when the room is surrounded by other rooms.
