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.
Now this setting type is available, it is a better UI.
This required a new setting class
admin_setting_configduration_with_advanced.
Also, I took the liberty of shortening the default auto-save delay to 1
minute, and re-wording the description of that setting, now that it can
be changed to any value.
This resolves problems when installing Moodle
and addons when preventexecpath active.
Please note the admin_setting_configfile is still
incorrectly restricted - this will be resolved by
MDL-40949.
When the destination draft area existed and the user draft area has not
been used, and thus does not exist, an error was displayed to the user
saying that they could not save the setting.
This was intended to handle the cases where the draft area disappears
and would overwrite the content of the destination area, deleting
all its content. But now we do not prompt with an error when
overwriting empty with empty.
Centralise management of all types of cron tasks with registration, scheduling,
parallel task conflicts(blocking) and running once off tasks, all using an
administration screen.

MDL-25504 cron: Refactor to use scheduler
MDL-25505: Add an admin interface to schedule tasks via cron.
