Code review: RLVa extensions are no longer optional features

  -> @accepttprequest will auto-accept all incoming teleport requests (allows exceptions - see @accepttp)
  -> @allowidle (stays experimental - subject to change)
  -> @getcommand:<filter> can be used to discover which commands are part of the user's RLVa implementation (with user-defined separator)
  -> @findfolders:<filter> works like @findfolder but will return all matches (with user-defined separator)
  -> @getdebug:<setting> can be used to query (but not set) the "RestrainedLoveforbidGiveToRLV", "RestrainedLoveNoSetEnv" and "WindLightUseAtmosShaders" debug settings
  -> @interact will block world interaction but allows drag-drop, the camera tool, mouse steering and access to the "self" context menu
  -> @sharedwear is the counterpart of @unsharedwear and wear locks the shared #RLV folder
  -> @sharedunwear is the counterpart of @unsharedunwear and remove locks the shared #RLV folder
  -> @touchhud will prevent the user from touching/clicking on their HUD attachments (allows exceptions)
  -> @tprequest will prevent the user from requesting teleports (allows exceptions - see @tplure)
  -> force wear commands will activate/deactivate gestures as well
  -> force wear commands will collect from folder links as well
  -> [FIXED] Location on incoming teleport requests isn't censored when @showloc restricted
  -> [FIXED] Message on outgoing teleport offers isn't censored when @startim restricted
  -> [FIXED] Message on outgoing teleport requests isn't censored when @sendim or @startim restricted
