Code reuse.
- Following routines: &recurse_options(), &build_javascript(),
&javascript_select_filler()
moved from coursecatalog.pm to courseclassifier.pm for re-use.
- New routines: &instcode_selectors_data(), &build_instcode_selectors
added to courseclassifier.pm to include code previously in
coursecatalog::instcode_course_selector() --
- New routine: &instcode_search_str() added to courseclassifier.pm to include
code previously in coursecatalog::search_official_courselist().
