Certificates: Additional flags for regenerate_user

* -G allows explicit setting of grade condition (e.g., a string such as
  'Distinction', 'Pass', 'F', 'B') for the certificate, regardless of
  grader output for the user.
* -T allows explicit request of a particular certificate template to be
  applied to a given user's certificate regeneration, i.e.:
    -T doctor_distinction.pdf
  to generate a certificate of distinction for doctors.

Fix incorrect parse of url in video_module.py

Sometimes the video url may look like 'http://abc.com/path/video.mp4?xxxx'.
(For example, the Windows Azure's media service will offer such type of url.)
The original code in video_module.py will produce 'mp4?xxxx' instead of 'mp4'
as the extension of a filename for such type of url, and therefore the video
will be non-playable. The fix here uses the built-in urlparse module to retrive
only the path component from a url and therefore the extension 'mp4' will be
correctly fetched.
