First full implementation of hardcore

hardcore receivers added and command added to chat.
Added chat command to hardcore; fixed menus

Many of the menus either had a "~Main Menu~" button only, or
selections dropped you out entirely. Now, the button reflects
the last menu, and most options do not take you out.
Also added a command to chat for hardcore.
Moved uncollapse process to async event

When someone winds up Dolly, they don't want to wait for the
next menu - so perform the uncollapse process as an asynchronous
event, not an inline function call. (Removed comment from
Transform.)
Added internal command to refresh RLV

RLV needs to be refreshed on startup - and who better than
StatusRLV? This script already has the entire RLV status
embodied in it...
Updated refreshRLV; converted TP to teleport

Updated refreshRLV to complete its task properly; converted the
internal command named TP to the name teleport (less likelyhood of
confusion or namespace collision). Worked on StatusRLV startup
process.
