Update password fields to work on 10.8 and 10.9

10.8 and 10.9 require a salt and iterations to be specified along with the password hash in order to work properly. This adds a salt, iterations, and correct hash for the password "puppet" on 10.8 and 10.9.

Note: I haven't tried that the extra options (salt and iterations) won't cause problems on older OS X versions.
