Window Staff

I've finished off the staff window. It has been rebased to the newer project layout so should merge in fine. 
Also added the fire staff prompt.

~~There is a small bug to do with entertainer costumes but I don't think its from this window. I think it is a mistake in the scenery functions. The bug is that the entertainer costumes are not related to the level.~~ Seems that is wrong after testing the original. Just a bit odd that some scenarios start with a gorilla but you can't make more of them.
