Rewrite the atto plugin loader so that:
A) We have a real settings.php page and can edit the toolbar.
B) All plugins are loaded at the same time (not serially)
C) All plugins share the YUI sandbox (more performance boost).
I had to change the loading API for this - but there are not non-core uses yet,
this is the best time to break it.
This is an alternative to the TinyMCE text editor that is based on HTML5
content editable regions.
It has been designed to "gel" with Moodle and uses YUI for javascript,
Moodle standard dialogs and standard moodle buttons. It has also been designed
to work well on mobile devices and can collapse down to a narrow column if required.
