- .registry is part of 'self' (the Titan plugin frame) which works great for Titan specific plugins.
  Titan plugins create the registry as part of the frame _OnLoad.
  But this does not work for LDB buttons. The frame is created THEN the registry is added to the frame.
- Any read of the registry must assume it may not exist. Also assume the registry could be updated after this routine.
- This is called when a Titan plugin frame is created. Normally these are held until the player 'enters world' then the plugin is registered.
  Sometimes plugin frames are created after this process. Right now only LDB plugins are handled. If someone where to start creating Titan frames after the registration process were complete then it would fail to be registered...
-!For LDB plugins the 'registry' is attached to the frame AFTER the frame is created...
