Improvements for AI Opponents

[thejeff]

You define casters as people who have magic paths. More importantly you define non-casters as those without magic paths. You don't give the non-casters path booster items (with exceptions for those have other boosts) or penetration items etc.

This is a much more basic fix suggestion than trying to build SCs or thugs. Just don't give commanders items that are useless to them or actively crippling.
