Bendy Bones: At last, it works!

I've gone through making a bunch of changes (mostly, just reverting quite a few
things back to their pre-patch state, and adding in a few other bits), and it
finally looks like it actually works for both BlenRig and the test files. Yay!

(Things are still quite messy, with a lot of commented out leftovers and stuff
to deal with, which I'll clean up in a moment after verifying that it all actually
works for real)
