New Gunner weapon

since the drum mags were removed, I thought about it being a good idea to add a preset AK with a drup mag and bypod to the gunner class (insurgents)

Just bring back the RPK!

Just bring back the RPK and the FAL+ext. mags from Insurgency 2.

RPK, FAL Heavy Barrel, RPD would fit in too, HK21e (because G3)
