As to the conquered races, over time, their political status will change from Vanquished
(if surrender is due to orbital bombardment) to Conquered, to Subjugated, to Occupied,
to Candidate Population, and finally to Imperial Population. The Planet's production rates
increase with every status change until the rate hits 100% with Imperial Population. Once
they hit that, they are your's, body and soul. BWAHAHAHA! Er....'scuse me.
