Floor Exit Sequence (v0.16a)

Currently, you just go back to the same floor but in the future, it will choose a random floor (that isn't the one you're leaving).

The actual visuals for the hole will need to be updated. For one the hole is affected by lighting which breaks the illusion of depth, but for two I would like to make it look like a set piece, perhaps a broken well or something. This way each floor could also decorate their exits in different ways.

Side note: it might be cool to have specific exits lead to specific floors. Such as a well always going to a water floor.
