Library interfaces finally removed, except for CMLibrary which was moved to the common interface folder.
Room positions more or less completed for the time being. Lots to grow and build onto it, but the basic structure should be done. Go command is mostly complete... I should make the default distance stop upon entering a room or something similar, I think.
REMaps have been replaced with ExitInstances. More of an upgrade of REMaps than a change. Exits create/manage ExitInstances which exist in rooms and are placeable.
Misc. other small changes and fixes as usual.
