Title: Add support for MathJax. 

Load MathJax.js if document contains :stem: attribute.

Sidenote:
Only thing that I am not so happy with is that the code is nearly a copy of the part in the html5 backend, except for translating plain ruby to slim. If integration of MathJax changes one day both converters have to be touched.
