Rocky Torterra Variants [Cobblemon]

Fixed the problem with the Nether Geoterra variants:

• They now naturally spawn in all Nether biomes.
• When evolving Gravtle into a Nether variant, you must now do it in the Nether.

Other fixes:

• The learned moves upon evolution have been removed, but are now egg moves.
• The consummation of the ore after evolution is now a feature, not a glitch lol.
