add dry-run mode and -u|--uuid for disk uuid instead of hard-coded sdN #16

It's to have: (1) -n|--dry-run in RSYNC_OPTIONS (2) -u|--uuid indicating a disk UUID instead of hard-coded sdN (in case of using cron job and disk table changed after power down => very very dangerous). Using blkid command to query disk label based on UUID is more tolerant.
