. Upgraded server to Ubuntu 16.04.1 (with Java 8, Tomcat 8, and PostgreSQL 9.5).

. Updated Java libraries to the latest versions and replaced deprecated code. In particular, replaced Velocity with FreeMarker, and replaced Hibernate schema generation with the JPA 2.1 standard one.

. Updated jQuery, jQuery UI, and Highcharts to the latest versions, and switched to using CDN for JavaScript libraries when possible.

. Added a Jackson HTTP Message Converter and cleaned up some AJAX code on the server side.

. Rewrote the Program functions for the college advisement project. This is a work in progress: department program functions are in place; no personal program functions yet; some old program functions are disabled and will be replaced.

. Allow cloning a class site of a different course (useful for cloning a quarter class site for a semester class).

. Use GET method for wiki search (can use browser back button to go back).

. Allow setting ymin and ymax manually for survey charts (sometimes Hightcharts chooses 6 when the actual max should be 5).

. Fixed a bug in File IO.
