Added new functions to editor api - set/get_text so the
original form text can be determined from an editor.

When calling use_editor() you should first call set_text() with
the text that will be inserted in the form element.

There is also a new scheduled task for cleaning Atto autosave drafts.

The logo for the clean and more themes will only be
displayed on the front page and login page as it was
replacing the header information on other pages within
Moodle, causing users to lose information on the page.

Singleview only supports grade editors not viewers at this time.

If the files in the draft area have been modified more recently than the timestamp
of the draft - do not restore the files, or you will delete any newer files. We
cannot really guess here - merging the 2 lists of files will be wrong.

If the student shares a course with another student then let them
see the same detail on the full profile page as they do on the
course profile page.

When using "sum of grades" and $grademax is zero, a division by zero
error occurs in fill_contributions_column() in
grade/report/user/lib.php.
