Turn metal tank into a container.

Also changed volume to reflect holding capacity.
Store fuel on metal tank when removing from vehicle.

Fuel will be stored in a metal tank when it is removed from a vehicle.
Two things to note about this:
    * It will store as much as it can in the tank instead of figuring
      out how much it was holding before
    * The metal will be put on the players inventory so to be able to
      get a reference to it.

These two issues should be worked on in the future.
Use the actual fuel amount in the tank for the refill.

Removing tanks will now remember the amount amount of fuel in them now instead
of being completely filled.
Spawn metal tank on the ground after removal.
Fingertip razors.

Passive bionic that adds a small amount of slashing damage to unarmed
attacks.
Protective eye lenses.
Zaweri's new reloading materials.

Appears to add solder, silver, bismuth and tin, for the purpose of using
them (along with gold) to reload casings of ammo. I didn't look too
closely, but did run jsonlint; direct any issues to Zaweri.
Empty commit, to test pull request jsonlint.
