Simple biomes

Adds simple biomes: grass (grass without reclaimable trees), sandstone (desert only) and arctic (ice only).

Added a new biome by Dissonant: small gas giant.

can we get the "reverse " too ? as in each biome having it´s dedicated reclaim?

You should add the hidden flag to the client mod to remove it from the Community Mods list and then remove the "Server" tag from the server mod's name.

This appears to stop every other biome mod from appearing in the System Designer biome dropdown. Any chance we can get that fixed?
