For now, I have made a separate format to handle these hashes.

I have committed my code to the "bleeding-jumbo" branch.

(https://github.com/magnumripper/JohnTheRipper/tree/bleeding-jumbo)

✗ ../run/john --format=blackberry-es10 -t
Benchmarking: blackberry-es10 [101x SHA-512]... DONE
Raw:    26758 c/s real, 27028 c/s virtual

Please let me know if you want to change the name of the plug-in (currently it
is blackberry-es10). Also, is the input hash format ($bbes10$hash$salt) OK?
