Brian Warner 9901a08fd3 Add dirnodes to backupdb and "tahoe backup", closes #606.
* backups now share dirnodes with any previous backup, in any location,
  so renames and moves are handled very efficiently
* "tahoe backup" no longer bothers reading the previous snapshot
* if you switch grids, you should delete ~/.tahoe/private/backupdb.sqlite,
  to force new uploads of all files and directories
