Using MathML markup

[Robert Lyon]

There is part of HTML5 called MathML https://en.wikipedia.org/wiki/MathML which is markup for math notation.

Currently we do math markup via the MathJax module - but it would be better if we could use the native markup option to do this.

But the main problem we have is that because we use HTMLPurifier to keep bad code out the MathML is stripped for content being saved.

To avoid this we would need to patch the HTMLPurifier with something like:

https://github.com/ezyang/htmlpurifier/pull/200/commits

Or wait until it is approved and merged in upstream.

I for one feel that we should switch to MathML and make the MathJax plugin obsolete

Seeing the problems we had with MathJax, a switch is worthwhile investigating further and seeing if we would lose anything that only MathJax could do.
