Joy Stipe in-world; multi-point leash

Notes for Multi-point/Satellite leash particle systems (by Joy Stipe)
- Command TO satellites is
llRegionSayTO (Wearer) - so that ONLY the collar wearer's stuff hears
ON (HUD_CHANNEL) - see state-entry for specifics
3-part message, begins with KEY (UUID) of target to leash TO
+ "\\LeashUp\\" - exactly as in the quotes, case sensitive
+ settings as a comma-seperated string (CSV)
OR (string)NULL_KEY + "\\Unleash"
It is up to the satellite script to "interpret" the message
and make/remove leash particles
