Fixed some of the initial critical issues

Added biome data insertion to insert chunk method of world builder
Added a check to the mod to prevent activation if the world is not
remote
The world creator now saves a default level.dat if one does not exist
Added calls to lighting methods when inserting chunks for world builder

Changed naming of some classes to more explicitly show that the classes
belong to GeoSharer. Namespace/Package were already distinct, but
Using/Import would make it difficult to tell things apart without hover
tooltips.
