Added student proposal review page. The proposals can now receive a score. Only org admins can assign a mentor. Every mentor can state if he wants to be a possible mentor (or be taken of this list). TODO's have been added for the access check, comment system and autocomplete. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed
