[Captain Kwok]

Yes, I did fix the Plasma Charge although I neglected to add it to the changelog.

Shadowstar, that is how it is suppose to be setup. Each empire's main script contains references for that AI to use specific weapons and to research those ones only. However it's not quite working right now so I temporarily added a bunch of common weapon techs to the global research list to at least make the regular AIs (non-racial ones) a bit more competitive.
