Allow Creating Multi-level Sets

[CDarrow]

It would be nice if, when hosting a game, you could compose a set of levels to be played end-to-end--Manes style, but pick anything.

Yes, please, very much so. This should support levels that don't have reactors or exits. For a level without an exit, everybody dies - no weapon carry-through. :-)
