[1.12.2] Variety of bugs I encountered while playing.

[Spearkiller]

End Iron, Gold, Copper, Tin, Silver, Lead.
Do not produce anything when placed into Purification Chamber or Chemical Injection Chamber.

End Diamond and Emerald:
Yield nothing upon being mined. Tested with a variety of pickaxes.
Can be mined with silk touch, however, which gives the ore.

End Lapis Ore:
Yields Ink Sacs when harvested.

End Coal:
Turns into 2 coal dust upon harvesting. Is effected by Fortune. This is probably intended, but seems silly to me as most other ores just yield the ore block. End Redstone also becomes dust when harvested, but IMO it should be like Nether Ores, in that all ores just drop themselves, and need to be manually processed.

Tested on 1.2.0-beta1.15
