Fix bug 1010022 - Change the unsubscribe message to sentence case
Make Django properly recognize HTTPS via mod_proxy in dev VM
Install django-allauth 0.16.1

* Add django-allauth to requirements, update vendor

* Initial configuration of allauth in settings.py

* Add allauth routes to urls.py

* Tweak to run both syncdb and South migrations in chief_deploy.py
  (allauth apparently needs both)

Conflicts:
	scripts/chief_deploy.py
	settings.py
	urls.py
	vendor
Use allauth 0.17.0. Update deps.
WIP
Remove custom email change views and templates.
Disable common signup by default.
Move URL patterns into /users/
A few more settings to enable similar behavior like current users app.
Use notifier for subscribe/unsubscribe to doc
Move gettext() to global where it should be
Made allauth migrations faster by using bulk inserts.
Removed devmo urlresolver prefixer as it's unused.
Minor cleanup edits.
Make contributor bar more efficient
Adding a class for FAQs and other groups of links.

Adding a class to be used for FAQs and other lists of links for further reading. I call it ".moreinfo"

Satisfying a small part of Bug #994029. I will communicate the class name and usage to Chris.

There is a testing page (https://developer.allizom.org/en-US/docs/User:stephaniehobson:moreinfo) that you can copy to your local dev if you like.
Moved newsletter view to users app and gut it.

This is in preparation to move the newsletter feature to the new signup flow.
Updated URL resolver to use startswith to decide which path needs a language redirect for nested paths
Minor cosmetic change.
Use separate subscription form in user profile view.

That makes the view DRY and easier to refactor.
