Adds four new weapons from the United Syndicates and the Federal
Technocracy.

Himeo has received two new guns based on the plasma cutter; the Guthrie
assault blaster and the Sabo-Tabby heavy blaster pistol. Both use a
hydrogen cell 'magazine' to mimic the more advanced, more accurate
Zavodskoi blasters on the market.

Galatea, likewise, has received the O61-B laser rifle pack set, an
export model of their own O61 Infantry Laser Rifle, and a gauss 'nitro
express' rifle, which fires tungsten slugs. Attempting to fire the O61
without a Galatean implant will result in consequences.

All sprites are my own handiwork, and all credit for the laser pack goes
to Alberyk for his work on the gatling gun. Matt and Schwann also
provided a great deal of help.
