Remake of the Generation
Platforms are now generated by biomes. A Biome can be seen as a certain
number of platforms wich are generated by certain rules.
Biome is an abstract class and there currently are a NormalBiome (wich
generates the same way as earlier everything would generate) and a
breaking platforms biome (wich generates only the breaking platforms).
the normal biome is used as a base biome and is always selected if
nothing else gets selected. The breaking platforms biome only gets
generated at scores greater than 540 and its length is randomly
selected, but it will always be between 20 and 30 platforms.
