More modular guns tweaks and fixes (#4221)

-fixes #4217
-lowers some of the component techs to make possible to get them
-fixes the phoron capacitor design having the wrong id
-modulator will now change the firing sound of the weapon, to avoid things like tasers and non lethals modules sounding like lasers
-fixes a bug with the random voidsuit picking the wrong helmet for the captain voidsuit
