Added passive radar/sonar for improved missile and torpedo detection.

I discovered that the 100mm cannons at each corner had half their autoloaders disconnected, and also that the RoF was way too high on them. RoF was reduced to maintain a constant rate, ammo capacity was doubled, and it wach changed to a 7/12-Sabot 5/12-Hollow/Frag mix.

I don't like shields, so I about halved their opacity.

150mm Disrupter rounds hand the single Frag warhead replaced with another EMP warhead, What it had before was too low for my liking.

Small boilers added, and idle burn rate of boilers increased. Ideally, this will reduce the amount of time that it takes for the energy production to keep up with the demand from shields.

Probably some assorted other changes from tweaking it while playing around, but nothing else memorable.
