The previous change on this issue accidentally fixed a selector,
so the repository API was recieving a valid node instead of null.
This means that it calls it's undocumented and dodgy callbacks on the node,
which are really calls directly to the TinyMCE API (just well buried).
But - by not setting the editor_target property, the api will not do
the secret handshakes.
If plugins try and do this themselves with Y.one, they will fall foul of the
qtype essay page bug which uses : in the id for form elements.
This is an alternative solution, to escaping the ids, which seemed unreliable for older
version of ie.
The cleanup rules are pulled from both testing of live docs, and the
jquery clean plugin. I tested with googledocs, libreoffice, word 2003
and word 2013.
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.
