2.7.1.0-RR
Repaired IDs and restored Nether Ores configs

The Nether Ores configs were redone and the new versions were being read, ignoring the old settings. This has been corrected (and the old versions have been removed from the config).

Whilst I was at it I corrected the mining levels for the materials now that's possible.

Force-spawning was also restored.
