Balance Mod

[ScottWAR]

I think this will be the final version, barring any imbalances that come to light with more playing.

This version (V1.3) adds two changes.
- Stealth Fighters And Bombers are no longer obtained by researching stealth. Instead Stealth Fighter I and Stealth Bomber I are avialable when Air Units 4 is researched. Stealth Fighter II and Stealth Bomber II are available when Air Units 5 is researched, and Stealth Fighter III and Stelath Bomber III are available when Air Units 6 is researched.
-Antiaircraft Truck I and Air Defense I are available at the beginning of the game instead of having to be researched first.
