Changes on 07-31-13:

• Up/down exits on High Guard Command now properly break groups when somebody wanders away.
• Custom socials involving hugs (or, presumably, punching) no longer cause tracebacks when invoked on droids.
• The ever crappy slip drive should no longer be vulnerable to infinite slips while waiting for user input and having somebody else access the controls.
• It is now slightly harder to screw up door submissions in such a way that it would generate a traceback when we try to review them. In the event that someone does manage to do so, the door will be removed automatically upon being reviewed.
