Minor bugfixes.

Updated to 2.6.

Anomalies will no longer appear on primitive worlds.

- Fixed planet names in Fallen Empire systems.
- Fixed a misaligned asteroid belt.
- The Preserve is a Gaia World again; the habitat thing wasn't as good as I thought it would be.

- Improved gas giant spawning in P-type binary and trinary systems.
- Gas giants generally have more moons now.
- Tweaked one of the trinary star combinations.

- Improved naming of primitive planets; they can now be named after the species living there.
- Improved appearance of White Dwarfs.
- Minor bugfix for binary/trinary asteroid systems.

- Empires can now start in binary/trinary Brown Dwarf systems.
- Added a new custom initializer, "Random Trinary III": the player's homeworld orbits a pair of stars, but a third is also present in the system.

Alpha Centauri A now has a small asteroid belt between its first and second planets.

- Slightly reduced the average number of planets per system (1 is the minimum number instead of 2).
- "Class D White Dwarfs" are now just called "White Dwarfs".
- Disabled one of the new trinary star combinations (Black Hole, Black Hole, White Dwarf) from random spawning due to bugginess.
- The guaranteed habitable world at Alpha Centauri can now orbit any of the three stars instead of just star A.

Minor bugfix.
