add option for disabling GT native metal deposits
fix name of GregtechGenNativeOres option
Original GT ores are only replaced when COG GT ore generation is enabled
dimension option files now contain only options set specifically for that
dimension (instead of all of them); also fix saving of options set via
console command, and options set in the GUI no longer persist as
overrides after creating the world
GT config no longer depends on options defined in MinecraftOres.xml
