Previously, these tests were skipped in order to support Django 1.4.

The site configurations can now set 'Profession' and 'Specialty' as
fields on the registration page.  The list of potential professions and
specialties to choice from can also be set from the site configurations
by setting 'PROFESSION_OPTIONS' and 'SPECIALTY_OPTIONS'.

Since we have started integrating with more clients, we have found that the usernames
that get passed are not compatible with our username restrictions. This PR introduces
a function to clean usernames to make them compatible, particularly in the auto registration
case.

Added fields to add social links to the user account settings file.
Added icons to the user profile when these links are set, only shown
when users show their entire profile. Added jasmine tests for account
settings and learner profile pages. Added python unit tests to test
validation on the user account.

Country Label was causing confusions for learners if it was country of origin or in which they
are living so changed it to a more appropriate message.

Also updated some other error messages to some more appropriate error messages.

In the reset password flow one can enter a single character password and subsequently cannot login to the site as password complexity is apparently enforced on the login page. Login page should not enforce password complexity.

In Python 2.7, `__file__` returns `.pyc` by default, this breaks our
comparison so let's strip out the trailing `c`.

Input forms that need validation will have AJAX requests
performed to get validation decisions live.

All but a few important and common form fields perform
generic validation; these will need a back-end handler
in the future in order to have them validated through AJAX requests.

Information is conveyed on focus and blur for both
errors and successes.

In particular, implement a validation API for registration,
where a client makes AJAX calls to the endpoints requesting
validation decisions on each input. Responses are strings
dependent on the type of validation error; if no error,
then empty string to indicate OK.

We have recently discovered that for any SSO Provider configured to skip
the registration form, we were auto checking the terms of service box,
which is a legal faux pas. Since IBM is planning to launch imminently and
is depending on this feature, we need to remedy this situation for enterprises
whose SSO Provider is configured to skip registration.

This PR hides all of the registration fields except TOS for this scenario
and disables the autoSubmit functionality that typically happens when skipping
registration.

Includes code for testing to be removed in the next commit.

with a custom patch needed by edx-platform.
Upgrade django-filter as well to v1.0.4
Import DjangoFilterBackend from the correct module - django_filter.
Add django-filter to INSTALLED_APPS.

Test all errors raised by account creation function as a result of
duplicate email/username will be caught, if the user somehow managed to
pass the first check, `check_account_exists`.

Previously, there was no catch for the AccountValidationError
exception raised by the account creation function. If, for some
reason, the user made it past the first check for a duplicate
username/email, then the exception was raised, uncaught, and
crashed the server.

Refactoring: Use format with named variables

PSA was monolothic, now split, with new features, like
a DB-backed partial pipeline. FB OAuth2 version also upped.

Partial pipelines don't get cleared except when necessary.
They persist for special cases like change of browser while
still mid-pipeline (i.e. email validation step).

Refactor, cleanup, and update of a lot of small things as well.

PLEASE NOTE the new `social_auth_partial` table.

When authenticating using an SAML IdP, gather additional user
data besides what is standard. Requires admin to input JSON
in settings to recognize the additional user data.
