Thaum Extraction

• Thaumcraft infused stone can now be extracted to obtain 3 shards of the applicable type. Can extract amber and cinnibar ore as well.
• Can white/black list dimensions for Pile of Rubble generation by changing configuration settings. Defaults for these settings essentially match current world gen behavior.
• Soylent Green can now drop as a result of PvP player death (i.e. one player killing another).
