More Diverse Maps 1.6.3

- Added settings to the More Diverse Maps Options screen to set biome size, biome size variation, and chances for spawning desert, plains and grassland biomes.
- Removed Noisy Continents Map, as it can now be created via setting biome size to 1 and variation to 0 in the settings.

- Changed maximum settable amount of mountains in the advanced options to 50, in order to avoid crashes from too many mountains.
- Added info about current Mountain & Scattering amount to the game pause menu.

Fixed mountain amount being potentially too high in multiplayer matches.

Fix for civ update 1.2.4
