Stage name: SensorSweep

Normal Sensor Sweep and Bioscanning, in Id order.

Note that when ExtendedSensorSweep is enabled, the mine scanning part of sensor sweep happens in MineSweeping, before movement. The wormhole scanning happens in WormholeScan.

This is a testing version.
It may be incomplete, and have more bugs (or features) than the public live version at planetscentral.com.
