Chased off != "Explored" + pirates are inconsistent

If you are chased off by another ship, the star system you just fled from should not be marked "Explored" - after all, you didn't actually explore it.

Good point.

Also, from the way the game behaves, it seems that space pirates are a planet encounter in and of themselves, instead of a planet obstacle like the robot drones or the Gloptians. This is odd and inconsistent with the other two events. Perhaps there could be a pirate base the pirate ship flees to or something like that?

Also a good point. The idea was that the pirate ship flies on after encountering you, but it never appears on the map to do so. There's another inconsistency I've already noticed, which is that the Gloptian cruiser simply vanishes when you bribe it. Surely it should either fly away or stick around but not block the system anymore.

Both are consequences of me not quite properly updating encounters when the game around them changes. I will endeavour to fix them in the next release.
