Add the Yugoslavian SKS 59/66 with Rifle Grenade Launcher.#3884

The Yugoslavian version of the SKS rifle has a rifle grenade launcher, which works by switching the rifle’s gas system to single shot, loading a rifle grenade onto the end of the barrel, and loading a blank.

It would be the first dual ammo weapon in game, firing both bullets and rifle grenades.

The grenades are also extremely versatile, coming in many variants: High explosive, fragmentation and even anti tank.
