OsSetSitActiveRange

• range > 0: if a avatar if far from the prim by more than that value, a sit request is silent ignored
• range == 0: disables this limit. Region default is used. Current that is unlimited if a sit target is set or physics can sit the avatar, otherwise 10m
• range < 0: sits are disabled. Requests are silently ignored

this value is stored on the prim, even if the script is removed
