Custom Cosmetic: Avali

* Backported better customization tag matching from Maelstrorca.
* Added Awle's Barn Owl Avali.
* Added Stock Concept Art Avali.
* ||Fixed pussy flesh color not being purple.||
* ||Disabled nipples on NSFW version (it looks stupid)||
* Fixed eyes not staying closed when sleeping or unconscious.
* Made eyes slowly close as torpor rises, this goes all the way from 0 to 200 torpor at which point the eyes are completely closed (and you fall unconscious even with max fortitude).
* Fixed Sandstorm not applying sand overlay over time.
* Fixed beer/troodon buff detection preventing the facial expression from working.
* Simplified blinking code.
