The Accessible.js config loads accessibility-menu extension which in
turn loads mathjax-sre.js library. There is a bug in this library
https://github.com/zorkow/speech-rule-engine/issues/182 that makes it
fail in RequireJS environments. This has been reported upstream as
https://github.com/mathjax/MathJax/issues/1854
As an immediate solution for now, this patch changes the default MathJax
configuration so that it does not load accessibility extensions at all.
JAWS Maths player does not recognise the math content when manually specifying the config for MathJax.
If you use one of the default config files it works.
So - we switch our config to the Accessible.js config that it is based off anyway.
There are no features changes with this approach.

filter/mathjaxloader/version.php
* Remove all traces of mathjax from the atto equation editor - it is filter agnostic
* Add a M.core.event module for core events that can be published/subscribed to by plugins (loose coupling)
* Add a FILTER_CONTENT_UPDATED event so plugins can tell the filter system when nodes are added to the page
* Implement a listener for this event in the MathJax filter
* Fire this event from the equation editor and from the glossary filter
* Add a nolink tag to the mathjax filter, so equations will not be processed by the other filters
* Add a smarter throttle function to the equation editor preview updates (Y.throttle is dumb)
