Rigify: new additions from PitchiPoy Animation Productions.

PitchiPoy Animation Productions is sharing its custom rig types
with the Blender community at large.  The new rig types all start
with "pitchipoy." and are used in PitchiPoy's productions.

Of particular interest is a face rig type for auto-rigging faces.
Other rig types include:
- Tentacles
- Fingers
- Arms/Legs
- Spine/Torso

Many thanks to PitchiPoy for their hard work and for sharing this back!
