Fix metadata inheritance

* bodyclass block got accidentally deleted

* with xml datastore, re-do all inheritance once the whole course is loaded

fixed course name title bar bug

Feature/victor/course grade detail

* need to actually return 404 codes to clients when DEBUG=False
* add option to make nose more verbose and drop to pdb on error

* dashboard links to gradebook and dummy grade summary page

* don't display thousands of '%' characters
* s/percentage/fraction/, since that's what it is

* also added todo about need for pagination

* required some refactoring in create_account() view

* also adds a comment to lms/urls.py

Did a quick security scan through views.

* we appear to be fairly consistent in using is_staff and has_staff_access_to_course
* cleaned up some docstrings and little code things as I went
* fixed small bug in change_enrollment view (check for non-anon user)

When in debug mode, check the staticfiles.finders before mangling urls
ok, confirmed working.  thanks.

* use url_name to compare to passed params
* remove unused fields from template context
* Also make it possible to link to a chapter

Make templates render on non-xml modulestores
