Forgotten password and username workflow for CrowdID

The password reset workflow in the CrowdID UI should work the same way as in the Crowd User Console.

This is what happens at the moment:

1. User goes to CrowdID login screen and clicks 'Forgotten your password'.
2. The 'Reset Your Password' screen appears. See screenshot 1.
3. User enters their username and clicks 'Continue'.
4. Screen appears saying their password is on the way. See screenshot 2.
5. Email arrives. Here is the email it generated for 'arthur':
