Removed redundant and unhelpful debug verb...



Because now the creatures start a loop for digging from the beginning. I'd
like to find a better way to do this in the future, but for now it works;
and that is what I'm trying to get done.

Digging code commented...



Commenting isn't my strong suit, so I just used a similar format to the
original programmer. Commented and prepared, loved and fixed, and now
is ready to actually be used.
