Added ClearFaceGenData to FFUtils.

This will clear out the copied FaceGenData from CharGen so a newly created character doesn't pick up the DDS/NIF of one from another save. Not merging with the dev branch just yet though since c++ isn't my schtick.
As expected Brendan had several ideas for improvement.
Merge branch 'newffutils' into dev-1.1.x
