Bug fixes and new features
Release notes: 

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).
