Subject: Generalized upper/lower layer map rendering

Map layers can have a flag on them that specifies that they should be rendered as part of the upper set (rendered above the normal sprite layer but below the above sprite layer).

Also added map connections between hallucination_interior and hallucination_cliff. And named the layers in the map files bc why not.
