Bug fixes and new features
Release notes: 

Fixed minor bug in student_search, where the red checkmark was appearing for a "blank" advising session.

Fixed minor bug in course_search module, which was causing an error to occur if the semester num was not numeric.

Added new field "extra_data" to the student_degrees table, to help module developers. Ex: banner_integration. This field is optional.

Added new permission to the course search module as well as the blank degrees module,
controlling who can access the course search/blank degrees, rather than it being assumed to be everyone.
