Face slapper update
- One less prim.
- Slightly lower complexity (root prim is a simple mesh cube now and textures are cleared)
- Added several configuration switches to turn emotes on/off and disable the slapper reddening for hood users.
- LLURL based names so people’s display names look nice and clean.
- Fixed an error in the fading code, it should be slower now, and proportional to the amount of slaps received.
