Particles now are generated from subsurfed coordinates.

Note that the current default generates particles based on the original
amount of vertices and faces, this for vertex group support (which is not
subdivided with modifiers). That means that particles generated on
subsurfed faces still have minor approximation errors.

Note for DerivedMesh users; I've added a new API call:
	float *mesh_get_mapped_verts_nors(Object *ob);
Which returns an array of 2 * 3 * float size, containing the vertices and
normals, deformed and subsurfered, but only the original me->mvert amount.
Works in all non-editmode cases.

Is in use now for vertex/weight paint and particles.
