[PR] Adds the taser rifle, replaces taser shotgun in Sec Control loadout

[Wisecrack34]

I'd make the single shot more useful or simply outright remove it. How about either lowering the cost of a single shot to half of the cost of a burst or if you wanna get fancy, perhaps have it shoot one larger slower projectile that does the effect of all 3 shots? Otherwise I like this idea 100%
