Acceptance_static is used to prevent collect static from using a seed
test.py had its seed removed due to redundancy

Fixed broken tests.  Made the hint manager enabled in testing environments - this lets us test the hint manager.

* Changed unicode test cases to ascii encoding
* Removed 'stanford' hardcoding in TOS logic in lieu of
  'SHIB_DISABLE_TOS' MIT_FEATURES flag
* made 'external_auth' always an installed_app in lms
* log.exception changd to log.error where appropriate

But: did not change skipping tests to changing settings, for
reasons stated here:
https://github.com/edx/edx-platform/pull/67#issuecomment-19790330

Highlights:
* The url '/shib-login/' interfaces with apache/mod_shib via
  request.META to handle shibboleth login and registrations
* Courses can designate 'enrollment_domains' to limit enrollment
  to users with a linked ExternalAuthMap verified by a particular
  identity provider
* Tests
* Logging

Refactor tracking and xqueue initialization to no longer require a request.  Get tracking logs to work.  Add transaction annotations.

Make sure to read only once from result objects when getting result status,
so that values are consistent.

Create a mixin class that can be used for tests that customize urls.py
to force django to reload it, so that they don't break other tests.

Start linting envs files, add task to only pylint errors, and move pylintrc file to the correct location

Use setup.cfg to set up default settings when running nose tests. Enable
the rednose library to color test output.

use django caching to hold computed metadata inheritence. Also invalidate the cache entries on writes (insert, updates)

- this may not be a good idea, but needed for testing cohorts for now...
