Made some changes to StudentProposal. Abstract is now required and content field has been added. New is now the default status. This will be used to easily distinguish between applications that didn't have their initial ranking/scoring yet. 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. :)
