Update to forge 1126, fix a nasty server crash and oredict crash

PacketHandler.getPlayer() now uses the proxies to return the proper EntityPlayer instance, no more server crash
OreDictCache is updated to the new inner workings of the OreDictionary
I had to comment out the line in the main Mekanism file where the lit_redstone_ore is added to the dictionary, it was causing unidentifiable crashes!
