Hidden Cache locations

Confirming that going back to Aurora (alex) is necessary first before going to Heph for the caches.

It's not really a cache location but in the Pegasus System you can hunt down pirate freighters that come through the gate. They are escorted so don't try this too early. The interesting thing is that these freighters drop pirate ships from Gen 1 to 4. And they have this awesome blood red pirate colour.
