Rearranged some of the code.
Removed unnecessary stuff
Made the fire adjust to fuel level

And other stuff ;3
Made rod appear only when you are cooking items
Added javadoc, changed it to use meta only.

Fuel level, some other stuff. Might be some debug println(); in there :P
Merge pull request #5 from xulufworld/master

Fuel level and flame size, plus other stuff. Issue #4
