Integration overhaul

* Removed api dependencies where possible.
* Removed unused integration classes. (Commented code need not be retained as it is recallable from the git repo.)
* Converted integration nodes to plugins.
* Rewrote TreeCapitator integration to be more efficient
* Rewrote ComputerCraft integration to survey all ores automatically. Makes new turtles when possible when new ores are added. Will benefit from #117.

@odininon this should be clean and is ready if it is. If it is no longer a clean merge, please let me know
