Mod Compatibility & Creative Tab Rever (Fixes #283)

ItemStack API was updated in 1.5+ and the wildcard value for metadata changed from -1 to Short.MAX_VALUE. Saplings can now be used in forestry's fermenter or to be made into ic2 plantballs, while logs can be used cooked in the coke over once more.

No more invalid ghost sapling showing up in NEI, because of an icon array that was one element to large.

Creative tab creation was moved back to the server side due to it being created after blocks tried to add themselves to it. I don't know enough about forge's initialization order at the moment.
