Add missing files registration

Change comment wrt. node numbering

Rename possible hair parametrizations

With this change, I think they're clearer and better follow Pharr's book.

Also change default to direct coloring.

GSoC 2018: port Lukas Stockner's hair patch

Still missing:
- some SSE ops which he disabled (I don't know why, so I didn't add
that)
- in svm_tex_coord, he invalidated NODE_TEXCO_WINDOW initialization (I
don't know why again)
- no change of util_color.h ops
- no change of nodeitems_builtin.py (XCode didn't find it in the
project)
