Add in an ItemStackHolder - a way to inject ItemStacks without having to have complex lookup code everywhere.

    Example: https://gist.github.com/cpw/9af398451a20459ac263

That is the latest forge release for 1.7.10 as of 05/30/2015 02:23:58 PM.

Well that's cool and all but I'm pretty sure this is only in 1.8 and I have no intention of developing on that anytime soon. Thanks for the info though, could prove handy in future
