Instructional Offering Configuration: New GWT-based Page

- Instructional Offering Configuration page rewritten to GWT to make the page faster and more reliable
  - to use the old (Struts2-based) page, set unitime.legacy.course.instr_offering_config to true

- also, when managing department is changed, only remove preferences that no longer apply (e.g., keep global room feature/group preferences)
  - former behavior (clear all room-related preferences) set unitime.legacy.course.clear_preferences to true
- also applies to Multiple Class Setup page (but in both cases, only when the new GWT-based page is used)
