Small update for billboards:

Browse Source 
* Renamed the old split uv's animate option "time" to "age" and added a new option to change the used split frame by frame. These are good changes were suggested/implied by Hannu Hoffren over 3 years ago in his tutorial video! (oh my how time flies)
* Also cleaned up the billboard ui quite a bit. For example now the uv channels can be properly chosen from the existing channels.
