triangulate any n-gons

[meszaros-lajos-gyorgy]

Arx can only handle triangles and quads, more complex planes need to be sliced up into smaller triangles. Should be done on threejs level.

Fan triangulation is a no go, because Arx uses vertex lighting, which focuses lighting information into the tips of the triangles. Something more evenly distributed is needed.
