Facial expression rework (Patreon)

In the past week we revamped Erika's facial rig. With some tweaks to geometry and subjoint system she is more lively than ever - at least enough to spice up an otherwise boring blowjob.

Unreal Engine 4 updated to 4.14 and we kept pace. However Nvidia hairworks and Apex Physics does not work as desired as in previous builds. We will wait for a few days to see if Epic would release a hotfix - if not, we will roll back and pack 1.10 with ealier engine version.
