Fix: Updated/Added 3 crashed Factorum ships (maybe shot down by the DFAC?) to Planetary Encounters. With different loads onboard, the previous update was missing some of the loot.

Tuned down the spawn rate for the PE's, it was in debug rate.

Added the first two Planetary Encounter, two Factorum ships shot down ;)
Tuned the size of the spawn groups for current Global Encounters

New ship and encounters added.
Spawn Frequency tuned a little higher on the easier encounters

Fixed bug: Global GPS not enabled on all encounters
Increased spawn rate, they should now start popping up
Made all Dark Factorum Thrusters nonpublic

Updated all ships with some new engines and slightly increased spawn chance of the DFAC encounters
