Added a bunch of new xmls and csvs. Added guards, doors and keys for first 8
levels. Change editor state to always snap to a square. Change Level.as so that
we don't need to store redundent names for floors and walls in every level xml.
Change variables of xmls to be double digit, i.e. Level01, Level02, etc...
