Runtime Map Loading (#3597)

changes:

Maps are no longer compiled in, instead loaded directly from the DMMs at runtime.
Z level defines have been moved from the config to map datums.
Unit tests now use typecaches.
DMMS now actually works.
DMMS has been updated slightly.
DMMS is now capable of loading simple lists of non-text types.
DMMS is now faster when loading many types without mapped in attributes and when loading area instances.
Asteroid generation is now defined on the map datum instead of being hard-coded in SSasteroid.
Holodeck presets are now defined on the map datum.
Atmos machinery now uses Initialize().
