It's hard to find all the possible ores

[skwerlman]

It'd be nice if TMGDO wrote a list of all the ores in the oredictionary to a file.

It'd be even better if those ores were sorted by which ore they provide.

Example:

# ore.copper:
#     Artifice:tile.artifice.orecopper
#     IC2:blockOreCopper
#     bluepower:copper_ore
