First part of dynamic root passwords. This is just the code that 

returns the hash of the password that is stored in the DB (or
generates a new one if one does not exist, and then stores it). Bumped
the version number too since I added an interval for it to the
watchdoginfo command. This stuff can run on the server, does not
affect existing images.
