#40 User management overhaul

[Bob Weigel]

User management overhaul - Possibly use OpenID or OAUTH, but there needs to be
an easy way to re-set passwords, etc.

At present, user information is stored in SQL db. Consider using native Java db: http://www.h2database.com/html/tutorial.html

Must be easy to re-set passwords, etc. Consider storing user preference information in eXist as XML document and then only minimal private info such as username, password, and email in user db.
