battle count for battle/siege attack group composition

con and combat counts to countbehaviour
seperate breakthrough from siege

add jammer towers
prevent antinukes, shields, and jammers from building on low-priority
turtles
treat buildassist bots/vehicles differently than con units (build more
of them)
use build pos, not builder pos for assist summon

- use build order position, not builder position for build assistance
- fix core bug having to do with not having lvl2 vehicle or lvl3 raiders
- dont switch cons to reclaiming if there's already a dedicated
reclaiming unit
- replace ai.totalCons with ai.nameCount
Merge pull request #25 from zoggop/master
