Added a singleton getter instead the public field.
Reduced all fields to private.
Replaced field access with getters.
Added setters where necessary (Dimension/Biome Registration)
Added config options to disable more features.
Splitted Enum name from the config key.
Changed FacadeConfig and Networkhandler similar to AEConfig.init().
Last (?) update pass. AE2 can be launched and used (?) in game.
Rendering system changed again and again - rendering is NOT working, to
be rewritten and CAN be done a lot simpler.
Second update pass which fixes all compile errors. Some parts may have
aftermath effect, hence why 3rd pass will check those maked with
"aftermath".
Errors: 82 -> 0. Mod can be launched.
