changed recipes

changed spud recipe to require only 1 material block & 3 sticks; added
"regular" blockID-based versions of recipes as well as "OreDict"
versions.
fixed up spud again

Now spud does what I want it to: harvests bark and only bark (no log
drops) from logs and bark bundles, and otherwise behaves as a generic
tool or player hand (slowly harvests harvestLevel 0 items). Removed
debugging messages from CraftingHandler. fixed BlockBark to not return
invalid metadata.
