Rewrites the area movement code used by shuttles & elevators in an effort to make it faster, more extensible, and generally easier to read. Also fixes some bugs relating to lighting & moving areas, such as lighting overlays suddenly being teleported into space for absolutely no reason. Fixes #2161. Fixes #2166.
