This was mostly tweaking test cases to be accommodating for variable sized superblock-lists. Though there were a few bugs that needed fixing: - Changed compact to use source dir for move since the original dir could have changed as a result of an expand. - Created copy of current directory so we don't overwrite ourselves during an internal commit update. Also made sure all of the test suites provide reproducable results when ran independently (the entry tests were behaving differently based on which tests were ran before). (Some where legitimate test failures)
