Updated material costs to match slot count

A somewhat major update. Reduced the size of the 4 big rear turret mounts to match the Astral. Changed the designs to mining turrets. Changed some of the internals to add more cargo space, from 6k to 9.5k... still not much. Also.... completly removed its torpedo capabilities.

A dedicated 10 slot warship variant will be uploaded to take its place as a combat vessel.

Fixed a mistake with one of the big turret points.
