[Off-hand Shotgun]

I had an idea for a mod so I thought I'd toss it out here and see if anyone bites.

The details of the mod would be:

• Adds an attachment in the weapons workbench for the Double Barreled shotgun
• Attaching this to your shotgun would cause it to equip to the grenade hotkey instead of your main hand
• When you use the grenade hotkey you pull out, fire, and stow your shotgun all in the same animation
