Add a generic method for getting a Keyname This patch will make logic/key_name.py obsolete in the future when everything is compliant with base.logic. This also makes the naming of already compliant logic modules generic and also fixes the _name field to be consistent with the naming in key_name.py. Note: This does not use Group/Sponsor, Group/School, Group/Organisation or Group/Club. Patch by: "Lennard de Rijk" <rijk0214@gmail.com> Reviewed by: Sverre Rabbelier
