MDL-15457 gradebook: fixing a regression, plain fetch() does not work with modules having multiple grade items per instance such as workshop

MDL-23876 Fixed a typo that prevented certain custom icons in activity modules; credit goes to Brandon Turner

MDL-24079 log migrated to new sql_like(), removing unnecessary preg test that had potential utf8 problem; removed extra '-'

MDL-23784 finally getting rid of all legacy .gif and .png extensions, yay! fixing issues with incorrect & in JS code

course/lib.php: MDL-23401 Fix regression introduced in MDL-23255 that prevents course creation when new course data doesn't include visibility info

This smells - IMHO auth_enrol should not do anything with the enrolment
related information. These two plugins seem to be tied too much...

MDL-23255 fixed inverted isset preventing visibility change in course edit form (creadit goes to Jay Knight) + fixed visibility of new course in hidden category when not allowed to change visibility; improved comments

MDL-22950 adding new component column to the files table, unfortunately this change requires changes in all 2.0dev code, please review all custom code that was already upgraded to 2.0; fixing multiple problems and regressions in mod/assignment

MDL-21782 reworked enrolment framework, the core infrastructure is in place, the basic plugins are all implemented; see the tracker issue for list of unfinished bits, expect more changes and improvements during the next week

we do not need any new api for fetching of course record - we have DML with MUST_EXIST flag which is the right way now; we should not include course/lib.php on each page anyway

By the way, the current style of creating course_sections is ugly. We
should probably have something like
make_sure_that_at_least_default_section_exists($courseid, $sectionid=null)
and not to insert it into database at many places as we do now.
