Quick Mod Proof of Concept for Tactical Game

[sage]

Hey folks,

I have some problems with the tactical game: my mass of ships fights his mass of ships, until someone wins. Not very exciting (though mercifully quick), nor is there any tactical depth.

1) All armed warships, and planet defense, with 2 exceptions, are 5x cost and upkeep. Build times are x2.
* This will reduce the number of ships fighting on the tactical map, and help avoid the 'ship cluster'.
* Scouts and survey ships have been increased as well.
* I am curious how the AI will handle this, since this also pulls the emphasis towards needing ground troops or specialty planet-attack ships for effective invasions.

2) Transport ships and arks have not received this increase.
* This is because I don't want to throw off the invasion mechanic.

3) Ships types now have variable top speeds, acceleration and turning speeding. This variation is quite significant; with only a few exceptions all ships previously defaulted to 1200 top speed, 300 accel and 180 turn. Now, it ranges from fighters III with a 1500, 600, 240 all the way down to much lower numbers for large heavier ships.
* Note that turning appears to be semi broken, as user clicks can cause even the slowest ships to turn 180 degree instantly, sometimes.
* Note that
