Stop forcing us to switch guns when we pick a new one up

@TeVVoids What gets me killed is say I have a 3x on my triple take and nothing on my flatline and I swap my triple take out for another weapon but the 3x gets automatically put onto my flatline so I pretty much die unless I can hitfire the next fight and find time to unequip and drop the 3x

@TeVVoids I pick up ammo, and it forces a new gun into my hands.

@d0JuTsu Not on a controller and especially not when its your main close range weapon you plan on using
