Updated RLV check handling etc

Removed some notecard processing, as well as a possible fix for
a double run of ifPermissions.... but mainly fixed RLV check
handling.
Removed rlvinit command

This command relies on restarting certain scripts among
other things - and its not clear if it works. Its being
supplanted by a menu button in any case. Some version of
this command could be reintroduced later if warranted.
Changed handling of 2 ~ folders

The ~nude folder and the ~normalself folder are now set elsewhere;
added a default as well as removed initialization in this module
of these two folders.
Added RLV On & RLV Off buttons

This button allows the Controllers or the Doll to turn on
and off RLV handling. This could be useful in some situations;
these buttons take the place of the '*RLV On*' button that
was present previously.
Changed Outift Search channel

The initial search for Outfits Folders was switched from
the generic channel to a newly created rlvChannel3; this
removes that channel from interference from other sources.
Added further documentation

Commented code further, slight optimization, and a rez event now
turns on processing, rather than off.
Extensive rework of RLV processing

Added default commands, processing of user* commands, and checked
and debugged RLV processing.
Slight fixup of RLV debugging and processing

Cleaned up slightly, and added moderate debugging to RLV processing.
fixed lmRunRLV() command

This command never put a script as the first element in the command
string - which is what the responders were expecting. Fixed.
Started added defines for Link Msgs

These are not in use yet, but will be added to link processing
in scripts in time.
