* add course and org to full/course.xml
* fix error path in clean_xml script
* commit rakefile change needed by c5334f150c

* use 'location' instead of 'id' in views.
* still need to change names in the coffeescript--quick fix didn't work

* test_{cms/lms} will run collectstatic first, fasttest_{cms/lms} won't
* also add staticfiles dir to test_root gitignore

* NOTE: successfully running the tests depends on an updated version of
  django-pipeline, which fixes a unicode bug (https://github.com/MITx/django-pipeline/commit/efaba4ac63bc635da6a728603e87e14758541ec7)

Config changes:
* Use separate db for the cms
* Run collectstatic before running tests--needed to get everything in the right place for loading pages
* fix some paths related to this
* Turn off JS compressor for CMS
* add empty test_root/uploads dir

Code changes:
* Add cms tests to check that home page and signup pages load
* Add cms account creation test
* Make github sync tests clean out repo dirs before running.

Make rake clobber remote test_root/*_repo directories that are used and should be cleaned up by tests

Usage: `rake cms:import DATA_DIR=<path_to_your_data_dir>`

Give a general purpose rake command for running django-admin in the right way for either the lms or the cms
