EXT-2769 EXT-2770 alpha masks not working properly

Eyes weren't alpha masked.
Hair wasn't being consistently alpha masked
Hair alpha mask was being ignored during avatar customization
We weren't hitting onFirstTEMessageReceived()

All of these were fixed. Also takes care of EXT-2926 EXT-2925 EXT-2974
