Support user profiles

[ojongerius]

If users are able to create an account we can save results for them. Have not thought about the implementation much, but raising this issue for the future and to link to it in related issue #60

Am doing a little POC with social logins from Facebook, Twitter and Github using social-auth-app-django. Looks promising, but needs a little polish, will do a test with saving urls for users as a next step.

Found a post talking about some of the options on user profiles, sounds like extending Django's User model with a one-on-one relationship is the way forward. Accessing the data from a view or template is super simple, not sure how we would store data from user actions yet. See https://simpleisbetterthancomplex.com/tutorial/2016/07/22/how-to-extend-django-user-model.html#onetoone

Holding off on further work on this one until I learn a little more about a possible collaboration, where user profiles already exist.
