Proxies to avoid crashes when the mod is dumped into a server's mods dir, fixes #2.
Added a bunch of vanilla blocks and items to the default black list, to act as terminators to avoid cycles in combination with mods that allow crafting vanilla stuff that can otherwise only be gained via worldgen.
Synchronized access to NEI's crafting info stuff.
Some cleanup and blacklisting TE's rockwool because the recursiveness in there kills the cost computation badly.
