Fixed Shotgun Shells

Interesting fact; The shotgun shells had the same IDST as the beta models.

Interesting fact 2; The shotgun you see in the screenshots is my Payday 2 trailer ripoff shotgun skin, I'll release that as soon as I find some way to stop the specular map from specular mapping everything.

Interesting fact 3; The shells come out of the wrong side of the shotgun.
