smw randomizer

SMW Randomizer Goals:

Phase 1: Randomize stages basically
	Single exit stages can only swap for single exit stages
	Double exit stages can only swap for double exit stages
	Switch palaces swap for switch palaces (might not be part of phase 1)
	Castles/forts swap for castles/forts

Phase 2: Randomize overworld tiles
	Castles/forts are interchangeable with single exit stages
	Ensure that the overworld tiles are changed appropriately
		(castle entrances should look like castles on the overworld)

Phase 3: Randomize tiles inside stages? Other randomizations here.
	Maybe change switch palace blocks?
	Maybe change blocks with powerups?
	Change some enemies in stages (gets into sprite gfx frustration)
	Suggestions?

Obviously works best for people with flash carts.
Should still be possible to have Any%, Any% NSW, 96 exit, 95 no cape, etc
	(95 no cape would probably benefit from an option to not move Donut Ghost House)
