Password reset functionality

[Briehan Lombaard]

Implement the functionality required for people to reset their password if they happen to forget it.

The process should more-or-less be like this:

• the user can click through from the login form to the reset form
• they then provide their email address
• if they enter a valid email address that belongs to an active user in the database we display a message saying that a reset link has been sent to their email address
• send out reset email with reset link
• they click on the reset link and we display a form where they can choose a new password
• once they have typed and submitted their new password we redirect them to the login page where they can log in using their new password
