Rewrite turtle block destroying

Browse Source 
- Try to make drop capturing a little more generic. This now allows for
   capturing a block's drop at a given position, as well as any drop
   within a bounding box (for things which don't play nicely).

 - Use as much of Minecraft's block breaking logic as possible,
   hopefully simplifying things and making it more consistent with other
   mods.
