[Idea] Xenon Level Up mod

[Shazbot01]

Yet another lets make the Xenon more spiffy idea incoming! The Xenon are only active in one random Xenon sector at a time. When their ships and stations get wiped out, they respawn in another Xenon sector with more stuff and are a little more aggressive then before. So you can either block them in their current sector to keep their current difficulty level, or use your fleet of warships to wipe out the Xenon in exchange for a greater challenge when they come back again.
