Aegis should mostly respect tech limitations so I'll ref #1964.
I'm going to go with #2364 is fixed, the AI should be more efficient in
early-game, and late-game is a known problem.
Fixes#2274 and fixes#2379.
Refs #2372 as it should fix several of those warnings for AIs.
Fixes#2256 with a new bartering system, in parts taken from mimo's
patch.
This was SVN commit r14582.
