rna api changes

- mesh.add_geometry(v, e, f)  --> mesh.vertices.add(tot), mesh.edges.add(tot), mesh.faces.add(tot)
- mesh.add_material(mat) --> mesh.materials.link(mat)

changed material.link so it always adds a material even if it exists in the list, this behavior is good for users but not scripts since it can mess up indicies (some formats may have the same material set twice).
