[CLOSED PR] Makes Signifer II stun mode fully automatic.

[DummySian]

I don't feel like making it work like normal taser/egun would be nice because it makes it like... Less unique? It will just make an egun with slightly different lethals and recharge...
NTSO already get full auto (Cornicen III) but it's ALL lethals, so NTSC getting full auto but stuns actually makes perfect sense to me
The signifer 'is it handgun or smg' description also gets a new meaning with this and it's pretty funny
I might consider burst mode making it fire multiple shots with one click but I want to hear devs opinion on this first
