Summary

Bugfixes "Fix gun shy trait"

Purpose of change

Even when your weapon is not a firearm, gun shy trait prevented you from shooting it. It also crashes the game when you try to fire any turret mounted weapon
And oh my god it crashes when you try to draw out(f) a weapon as well, so fixing tis as well
fixes #76651

Describe the solution

Add the firearm condition along with the gun shy trait in gunmode_checks_common
include holding a firearm in gunshy condition in fire() (this fixes the holster and turret issues as well)

Describe alternatives you've considered

All bows use gunpowder to shoot

Testing

Bows and other stuff work and game no longer crashes hen firing a turret/drawing out a weapon

Additional context

glad to see that im still squeezed onto seats as a normal sized character

Oh and the game crashes when I try to use a mounted gun which is troubling
Edit: Yup, fired up the dry version of latest experimental and it crashed with the trait as well.
