With tests, some settings changes
(all should default to not breaking anything for edx)

pep8 pylint

move logging/error handling from shoppingcart view to model

Addressing @dave changes

* Fix open redirect vulnerability
* Add Logging To AUDIT_LOG : Note I had to change existing tests
  that mocked AUDIT_LOG with this
* Use external_auth.views.SHIBBOLETH_DOMAIN_PREFIX in student.views
* Add a bunch of documentation
* PEP8 / Pylint

* If a shib users type in their email on the regular login page,
  redirects them to /shib-login/
* Modify student.views.accounts_login to handle redirects
  generated by @login_required for courses that use shib for
  access control.
  Redirect those logins to /shib-login/?next=

Features coming down the pipe will want to be able to:
* Refer to enrollments before they are actually activated (approval step).
* See what courses a user used to be enrolled in for when they re-enroll in
  the same course, or a different run of that course.
* Have different "modes" of enrolling in a course, representing things like
  honor certificate enrollment, auditing (no certs), etc.

This change adds an is_active flag and mode (with default being "honor").
The commit is only as large as it is because many parts of the codebase were
manipulating enrollments by adding and removing CourseEnrollment objects
directly. It was necessary to create classmethods on CourseEnrollment to
encapsulate this functionality and then port everything over to using them.

The migration to add columns has been tested on a prod replica, and seems to be
fine for running on a live system with single digit millions of rows of
enrollments.

Rename MITX_SETTING AUTOMATIC_AUTH_FOR_LOAD_TESTING -> AUTOMATIC_AUTH_FOR_TESTING because it will be used for acceptance testing also.

Remove _

Minor cleanup.

Add audit log definition, and use for logging of logins in external_auth and student apps.  Move test_login to student app. Improve conditional tests for Shibboleth login logic.  (Does not include reconfiguring log settings.)

remove test that csrf middleware is disabled (since we can't seem to reload middleware between tests)

move definitions from setuo into test method

The template exists when django admin is enabled, but the mappings in CMS' urls.py do not exist.

Changed to subclassing django's PasswordResetForm and
overriding clean_password() instead of copy/paste.
Less lines to worry about for diff-cover this way =)

migrations.

The most common error is Amazon SES having blacklisted an email address.
However, we handle any error being raised during user.email_user.

Fixes JIRA LMS-131

Django always returns string data from the database as unicode objects
(ref: https://docs.djangoproject.com/en/1.4/ref/unicode/#models).
Therefor, our factories should do the same

This allows specification of profile parameters when creating a user. Because
the profile contents are always accessed from the database, the user must be
saved to the database before the profile is created. This means that the
profile cannot be created if the user is merely being built (and not saved)
rather than created.

I moved the test into lms/courseware/tests so they run correctly.

strings.

Added unit tests that verify the fix.
