Bug fix for new move feature

Path for zfs diff bug and add move V feature

zfs diff has an issue that spaces in file names are replaced with \0040. Added patch to correct this condition. Also added feature to have a move flag for diffs (V). By default zfs diff returns R for Rename and Move but new flag on get_diffs allows for distinction between rename (R) and move (V).
