Vox and Plasmaman helmets no longer protect from flashes

Created by: icantthinkofanameritenow

Removes EYEPROT from civilian Vox and Plasmaman helmets (e.g. all but engineering and security). This will make them vulnerable to flashing despite being space helmets. Please note that this also removes their welder protection too, so please remember to wear welding goggles if you need to weld something and aren't one of those jobs at roundstart.
