This commit updates the map system to -tg- standards. All stations are
defined under _maps/, and all .dmm files go under _maps/map_files/.
Currently, only the NCS Cyberiad is setup under the system.
Misc changes:
- World Status contains the map name
- dm.sh script will allow automatic map changing between restarts.
- _globalvars folder starting to take shape, not everything is migrated
there yet.
