MDL-51179 Atto: Extend autosave fix to cover text changes
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.
