Speed up autopilot docking to stop huge queues.

Tested at TAF 16x in a variety of ships without scratching the paint.
Adjust populator settings and related AI a bit.

Main changes: more independent pirates in Feudal/Anarchy; repopulator has a cap on the number of ships it can accumulate in-system; certain ships have tendency towards awful or non-awful accuracy settings; independent pirate packs are slightly bigger; tharglets share accuracy of controller. Overall effect should be to make the difficulty slope between Corp and Anarchy larger, but Corp safer.
