Basic newsletter importing, not perfect but good enough.

Make url patterns more consistent

Closes #122

This addresses nearly all changes from the proposed urls.csv. However, the changes to the password reset URLs have not been implemented. We currently include `django.contrib.auth.urls` for all URLs related to authentication, and changing those would require including all of the individual URLs instead. For maintainability, I suggest we maintain the `reset` pattern instead of the (arguably more clear) `reset-password`.

See the discussion in issue #149; this evaluated get_language

Closes #149 

This potentially breaks what was achieved in !126. I gave it a superficial glance and it looked like the migration still works, but perhaps this could do with some more thorough checking.
