Made various changes for a new beta feature, so that students grades can be assigned to groups by best grade first.  Files affected
  were _CourseList.php, _Student.php, _FlightPath.php, advise.module, system.module.

  Adjusted the .install files which come with FlightPath core modules, to always provide a default value for fields.  This is because
  in MySQL strict mode, the installation fails if default values are not provided.

  Corrected a course_search.install, where it was recording a faculty_id as an int still, instead of varchar(30).
