Added the Firefly unit.

Small description fix

Added the Mortar mech. Pad requires slag to operate.
Added the Aqua Drill, a faster water extractor.
Added the Grenader unit.

*For real this time*
Now the Diamond Ruins Zone should be a working Attack map for the Campaign.

Another failed attempt to fix the campaign map.

Added Precision Diamond Drill and Barrage turret.

Still a bit stuck getting Diamond Ruins to be an attack mode Zone.

Added the Diamond Vault and Mass Distributer

Turret balance changes

Cryogem Update: Adds the Cryogem item; a solid chunk of compressed cryofluid that can be taken with you to space.
