Add more gun modifications.

[RanarTheWrathful]

Let me know if some of these do exist(and how to do them), I may have overlooked it.

• colored guns
• changing whether gun shows below or above tank, similar to turrets.
• Able to make the gun into a shape if you don't want to use aspect, width and height to build it.
  Thank you.
