A bunch of LUA autogen additions. (#235)
* A bunch of LUA autogen additions.
- Add support for Vec4f, Vec4s and Mat4 in the autogen.
- Improve error messages for improper argument counts
- Added support for more pointer types in the autogen.

* Fix offsets in sMat4Fields.

* autogen: Rework this at the request of DJ.
