0.8.9.5 - Fixes, tech tweaks

Version 0.8.9.5

Changes:

• Added particle emission to rig demo animation (barely visible) in order to compile shaders for particles at the start of game. Game may take longer to load, but shouldn't stutter on the first sneeze (especially on web).
• AllergyResource no longer has statistics, except for a name. AllergenDetectors now handle all the statistics for allergens and other particle type effects on a character level. Balancing may be altered from previous versions as a result, but the system should allow for more customization in the future.
• Particles should fade from both lifetime and tickle amount remaining.
• Cold system worked on a bit, now has a single slider for strength, and background curves for effect. Balancing in progress.

Fixes:

• Eyetracking shouldn't get stuck looking at the nose/up anymore, when going back to idle/tickle state.
