Update BlockOre.java so it properly drops coal when mined via machine (like Buildcraft)

The item drop code in BlockOre would drop the correct items if the block was mined with a pick, but if using some form of autominer (buildcraft quarry/miner) then coal blocks would drop Bituminous Coal or Lignite (depending on the ore).

See http://terrafirmacraft.com/f/topic/3864-164b7817buildcraft-tfc-crossover-mod-wip/?p=87349

This update will convert the item drop for BlockOre1:14 (Bituminous coal) and BlockOre1:15 (Lignite) into regular TFC coal when mined with a machine.  The modified functions are not actually called if players mine the ore themselves with a pickaxe so this is a compatibility update and has no effect on TFC by itself.

BlockOre2 and BlockOre3 are not affected by this.
