Changed cStructGenOreNests to take a list of ores + the block to replace.
Added NetherOreNests.
It generates Nether Quarts.
Added NaturalPatches generator
It generates gravel and dirt.
Bunch of tweaks:
Renamed Quarts to Quartz
Using const_iterator instead of iterator
Used CheckBasicStyle script to find style errors
