* Added Avatars.OnPointAt, Avatars.OnLookAt, and Avatars.OnEffect events for ViewerEffect packets
* ExportCommand can now export objects owned by the master
* ExportCommand can now optionally take only two arguments, and will export whatever object the master is pointing at (if permissions allow)
* Added a ShowEffectsCommand that shows all of the ViewerEffects the bot can see (VERY noisy)
* LookAtTarget enum is renamed to LookAtType
