Improved donkey rig (Patreon)

Here's a bunch of stuff on the improved rig. I've added:

-A tailhole

-Better nuts

-Breathing bones (automated by a driver)

-Improved pp controls

-Some other stuff

The eye lids were quite challenging >_> I had an issue with bone parenting and some weird deforming when the head was turned at extreme angles. So I went with using a shrink wrap constraint on the eye lid controller that wraps to a "shell" of the eye (to prevent the eye ball clipping through the lid).

Still need to:

-Add tilting eye lids/brow for emoting

-Soft body jiggle mesh for the butt

Also, I can't believe there are (checks screen) 60 of you wonderful patrons!? Thank you all so much :3 I should warn you though that progress will be slowing down soon as I start another semester next week which sucks but I'm nearing the end of my degree (only 3 semesters left counting the one coming up). 

I've been making some mad progress the last few days because I've been off from work and haven't had school so I've just been doing 3d stuff like crazy. And, I'd like to be done with the improvements to the donkey model and start improving the triceratops.

I think that the animations should still work on the improved rig since I didn't remove any important bones and only moved the hip bones a tad. And things like the improved sack deformation is automated via constraints and such. I haven't tested it yet- but I will tomorrow.

Until then!
