Adds a better name to hardhats.

Created by: FudgePucker

I found a little mistake with adding more hardhats to the vender on derelict, all the hard hats are called hard hats, other than the firefighting one. So in the vending menu it was; hard hat firefigher helmet hard hat hard hat hard hat

This should fix it so that everything isn't just hard hat.

Also for discussion is, should I add funny descriptions to the other hardhats? I was think for the white one it should be "Put this hard hat on your head to show everyone who is the head." Because Head of Engineering would be funny. Say the abbreviation out loud to yourself.
