Updated the current config's to use the new file name. All that needs
doing is for someone to texture the hearts of each log. The current one
looks weird as its the default one.

New Texture Format:
Leaves = leaves_{name}_fancy/fast
Log = log_{name}_side
Log Heart = log_{name}_heart
Plank = plank_{name}
Saplings = sapling_{name}
