Title: "Anomaly" Events!

Adds Anomalies, which appear as random events.
The bluespace, black hole, and flux wave events have been ported into the system as anomalies. The other two are new, for a total of 5.

Anomalies are effects with special powers. After a period, they disappear, though they can be manually neutralized.

You can neutralize an anomaly by first analyzing it with an analyzer. This will reveal the frequency it operates on. At that point, you or someone else can send a signal on that frequency to disable it.
Neutralizing an anomaly results in it dropping its anomaly core, which can be researched.

Certain anomalies, such as the flux wave and bluespace anomalies, have negative effects if they're not neutralized in time!

Design-wise, these events are intended to encourage crewmembers to react and respond to the event instead of it simply happening and cleaning up afterwards.
