0.8.5 - Sliders Update, Redness, Animation Tweaks

Fixed a breaking change I introduced in 0.8.4 - allergies should no longer damage sensitivity instead of adding particle counts!

I've re-implemented nose redness on tickle/burn for both nose hitboxes. 

Animation tree has been tweaked to allow animation repeats, and customize the chance of a repeat while doing that animation.

Slider categories are collapsible and scrollable, so I can start adding more!
