If a user is anonymous when they click the enroll button, they will automatically be enrolled in the course if they immediately log in our create an account.

Cleaned up the urls file a bit, to remove urls that don't work. Also removed some unused stuff from static_template_views.

Moved static template views to one folder. Removed the stub view functions from student and used static_template_views instead.

* don't know what the intended fix is

This reverts commit 05e1bcf4.

The basic form has been fleshed out. Things still to do:
1) Extend get_course interface to the rest of modulestore
2) Make courses actually load
3) Make org/course/maybe others metadata attributes for course_module (see xml_module), so
that they are loaded/saved on import/export to xml

These are then displayed at /courses.
