Increased Colony costs for "flavor"

[Suicide Junkie]

The rock/ice methane bug in sectortypes.txt does indeed make only a small effect.

The systemtypes.txt is where the huge issues crop up.
Far too many Rock/Any calls, not enough Ice/Any calls.
Rock/None is also far more common than Ice/None in the systemtypes.

The map analyser covers the effects from everything:
- sectortypes.txt
- systemtypes.txt
- quadranttypes.txt (choose one quadrant to analyse)
- settings.txt (the population modifiers to SY rate and resources)
- planetsizes.txt (facilities, population, domed planet modifiers)
