Models and API for users and contacts

[jwhitlock]

Add user and contact models Django-standard users may not be a good fit.

Users:

• username (optional, generated for end users)
• password (optional, for admin)
• first name, last name, preferred email (optional)

Phone contact:

• user
• phone number
• verification sent time (or null if not sent)
• verification time (or null if not verified)

Email contact:

• user
• email
• verification sent time
• verification time

The API should allow creating a user and associate contacts, lookup status of a contact, but no list of users or contact info.

It's a bit kitchen-sink, but I suggest django-allauth for this. It will give us email verification features and the ability to add registration via Facebook later.

There's two reasons to gather user info:

• Gauge interest in the platform
• Notify users of new / updated cases

This issue is all about the notifications, so I'm moving it to that milestone. If we want to setup a mailing list for changes to the project, that can be a new issue.
