Only consume power when a dimension is actually loaded (players present or chunks loaded)
Moved all parsing of dimension descriptor strings into the DimensionDescriptor class so that it is centralized and easier to change
Moved the terrain type 'spheres' to a feature type. Still not implemented but it is more a feature then a terrain.
Started implementing support for modifiers in dimlet descriptors
Fixed a bug constructing the descriptor string related to the new modifiers
Added several new material dimlets
Material modifier now works for generating terrain
Fixed the cost calculation so that modifiers are considered again
