Important update to fix IK issues (Patreon)

Hi everyone,

I'm confident that I finally figured out what was causing some of the IK issues some people were having lately like only the right hand not working.

This was actually caused by a long lasting issue with drivers and constraints dependencies that I didn't really know how to fix before. Going forward the models should be less prone to crashes and might have slightly better performance and more stable behavior in IK mode.

I've updated all the most recent models : Fortnite Chunli, Lulu, Morrigan, Azula, Joel, Jack and Rikku. 

I've also added the facerig to the models which didn't have it yet.

If you have the issue with an older model, the way to fix it is to make the IK bones show, then for each elbow and knee bone (IK targets shaped as cubes), replace the bone that is targeted by the bone contraint (foot or hand)  with its IK equivalent. So for example, rFoot will become rFootIK. That should be enough to fix the IK issues.
