[version constent issue and feature request] safeguard weapon clicks when interacting with GUI buttons_

[Shibva]

It appears that this happens with the 1.7.10 version as well. if you're holding a firearm and press a GUI button such as respawn and resume the game, it will cause the weapon to fire

it may not seem like a big deal; but when it comes down to weapons like the M42 Fat Man, well let a scare of a factory base blowing up and thinking it was my actual base be enough a scare and prove a point

oh on another note the old mini-nuke (that has not yet been completely replaced by the new ones is still generating the legacy ammunition
