FSS Event Handling

[Balvald]

[Balvald]

Relevant events are "FSSAllBodiesFound" and "FSSBodySignals".

Actually most important is "Scan":"AutoScan" (for stars) and "Scan":"Detailed" for planets.

FSS Discovery Scan is relatively useless for logging and savekeeping purposes.
FSSAllBodiesFound is neat to have as it signals that we finished a whole FSS scan for the system.
