* Added Arm Morey and Core Lamprey stealth submarines.
* Fixed a conflict that prevented the "Immolater" from firing.
* Added Arm Blackhawk and Core Harrier light attack helicopters
* Moved the Arm & Core Capital ships and the two Heavy carriers to a
   new Capital shipyard, built by the Construction ship.
* Added the massive Arm Man-o-war and Core Kraken Capital submarines, also
   found in the capital shipyard.
* Balanced the AI so that Core spends less time building useless structures.
* Revamped the Chevalier and Warspite class light cruisers. They look different, and behave      differently, and should be more effective versus submarines (because of the enhanced 
   weapons).
* Excaliber and Eldritch units now produce 500 energy each.
* The two heavy carriers are now more expensive, but also have twice the armour of before.
* Fixed a huge range problem with the Excaliber Main gun, Eldritch secondary gun, Circular 
   saw, and Archgun. Actual ranges were twice what they were listed as. A strange bug,
   but these weapons have now been fixed, meaning their range is much less than before.
* The Archgun and Circular saw weapons fire faster, at the new lesser range, and do less 
  damage per shot, but more overall (20% or so). Cost is unchanged.
