* Fix for diffing issue after rollback in
conjunction with created and deleted buckets.
* Changed rollback function to check against the full set of documents
for a revision instead of just the documents at that particular revision
* Created a document_delete function to encapsulate document deletion
* Added additional test case to check that a rollback to
something other than 0 deletes the created buckets in between
