Fixed enforcer job info showing up on habitat capital buildings for gestalt empires.

Fixed administrator jobs showing up on habitat capitals for gestalt empires.

Updated orbital habitat capital buildings so they work better with the larger populations supported by the mod.

Note: Changes should not be considered as final. This is a stop-gap measure to keep things functioning for now. Eventually a third tier of buildings should be added, and the earlier buildings nerfed a bit.

Now override all of 00_strategic_resources_tech.txt so that rare resource techs can appear when colonizing the right kind of habitat. Previously gas & crystals worked fine, but motes did not. For now the full file override seems to be the only solution.

Asteroid habitats have random sizes, but were supposed to be weighted toward the middle of the range...

Now they are.

added ice asteroids to the habitable_structure definition

Fixed and re-uploaded the planet-fixing script.

reverted last change, more testing needed

Added bi-yearly event that checks for planets that might have gotten messed up for any reason, and are no longer a habitat planet type but still have the modifier - and removes the modifier from them.

Planetary habitats start with the colony_event flag now, which should prevent most colony events from firing on them.
