[MIRROR] adds a gun circuit shell (#7934)

* adds a gun circuit shell (#61156)

adds the circuit gun shell, every projectile it hits with outputs the shot mob, everytime its shot charge from an attached circuit is transferred to it, it deals no damage
increases the range of the to string circuit to 7 tiles from 5, now should get everything in view range

* adds a gun circuit shell

* Update gun.dm
