1. BUGFIX: game setup/config. (Previously showing both maps instead of one for each ruleset)
2. Use variance fractal instead of RND for ice shelf and terrain boundaries. Purely aesthetic. Little to no impact.
3. Remove last of legacy Outback Tycoon code.

1. Made world age consistent between GS and standard/R&F maps.

Minor bugfix for GS ice generation. No impact to (land) map.

1. Support for GS (notably the Climate system).
2. Better central Great Plains generation.

1. Use Fractal map start defaults (instead of Pangea).
2. Bugfix: random World Age.

Fix reef gen. for R&F. More reef.

Add support for R&F.

Corrected advanced map option name and description for World Age & Rainfall. No impact on game or map.

More central American rainforest. (More cowbell!)

Added a northern forest bias. Also tweaked terrain and feature generation for more southern/central American rainforest.
