Version 0.5b fixes several bugs including:
AI Expansion / Shipbuilding (several bugs related to this)
Antaran X bug fixed that caused an X to be lost due to attrition while ships were inbound
Gofur's UI 1.2 and Combat FX+ 2.0 removed due to size concerns
Removed all sensors / ecm / cloaks to remove visibility issues until a suitable fix can be found.
Also fixed system ships, a problem which was causing MAJOR piracy issues.
Some other minor changes, details are in the readme.
