Moving to openmrs
Now includes an additional anonymised dump encrypted with an independent key

Hero now does this:
 1. Dumps the openmrs db
 2. Reloads the dump in a separate db called anonymiser
 3. Runs some SQL to remove personally identifiable information
 4. Re-dumps the anonymised db
 5. Compresses and encrypts the *non* anonymised dump with the UB Ops
key (EEABA323)
 6. Tarballs and compresses the temp directory and /var/log
 7. Encrypts the parent archive with the UB Anonymous Data key
(7496054D).

Both encrypted archives are signed by Kasha (7FCE6178).

Example directory structure of the archive:
