Finish emotes

Emotes require 2 bytes per char. They're encoded into the region
[0xE000, infinity). The texture is 4k, and uses 1k vertical pixels
per emote segment, for a maximum of 32 segments.

* Reduce volume of noise indicator by 90%. Quiet is probably better.
  Might want to add a volume slider idk.
* Bugfix: emotes without a transparency channel now work
* Address a couple Unity performance complaints about the shader
