Allow users to reset their own passwords via an email link

[jniles]

We are getting more and more users who should be able to reset their own passwords or configure their own passwords. In the example of the health zones, we will have lots of users who will need to reset their own passwords without needing to go through a whole helpdesk setup. We could set up a "reset by email" system that allows users to click a link to reset their password.

We probably will need to set a user's "preferred language" in this case, so that we know what language to email them in.
