Org applications can now only be made by a user when a program allows it. To do this a new access_type has been added called apply. This ensures that users can only used the seeded version of create. Also the review_overview now has his own access type to ensure the separability of hosts for different sponsors in case of org app reviews. Note that the access checks for hosts are broken and only give access to developers at the moment. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed

"""
Pages in Django can are served up with custom HTTP headers containing useful
information about those pages -- namely, the content type and object ID.

This module contains utility functions for retrieving and doing interesting
things with these special "X-Headers" (so called because the HTTP spec demands
that custom headers are prefixed with "X-").

Next time you're at slashdot.org, watch out for X-Fry and X-Bender. :)
