Fixed issue 205. Registered students can't apply to become an organization. If for some reason the org sign up period and student sign up period are run in parallel and a student has applied to become an org, the application will still go through the normal system. Although the student won't be able to become an org admin until he has been invalidated as a student. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed
