[DGD] Kotaka 0.22

[Raymond Jennings]

Changes:

Game no longer automatically boots Intermud, this is now left at the
discretion of the mud administrator

Geometry subsystem created, will be used in the future to confine geometry
related code and move it out of Game.  This decision was made because it's
not really game specific.

Upgrade instructions to migrate in game objects to the new Geometry
subsystem are found in ~Game/upgrade.txt once files are updated to v0.22.
 Migration code and old state will be removed in v0.23

Also, the mudmake script has been fixed a bit to make the name of the mud
directory configurable.
