Oldschool m4 fix

So yeah, as requested I've produced the same fix for moddefreak's oldschool m4. This one was a bit more difficult to produce and I actually needed to use blender this time. If you notice any issues with the release don't hesitate to inform me and I'll upload a part 2 because I'm not very good with blender... Oh yeah and I actually uploaded it in the appropriate class this time.
