Fix this file so that hotkey 3 works to switch to "onBack" primary weapon when DZE_TwoPrimaries == 2. Add optimizations and rework function dz_fn_switchWeapon_swapSecure. Remove mutex. It was not doing anything.
The addAction click was doing an animation without switching when the
player had a primary or melee on back but nothing in hands.
Probably present in vanilla too, will check later.
