Added triangulation library and rift render

Major change is addition of fractal rift rendering, currently first
pass.

Curves are registered and pregenerated in mod_pocketDim.

Rifts look up these curves, choose one, rotate it, and render it.

The render is a TESR that does stuff. Hard to explain, look at
RenderRift in the code and look at the actual rifts in game to get an
idea of what it does.

I had to add a triangulation library to accomplish this. Will hopefully
do something else  that drag around all this.

(I tried(and used comments))
