Verical line in MathJax LaTeX equations in FEniCS Q&A

[Michal Habera]

In Chrome-engine based web browsers, the MathJax v2.2 shows extra verical line. This is related to the known issue https://github.com/mathjax/MathJax/issues/1300

This issue was resolved in MathJax v2.6, so please replace MathJax with the new version. I can't find FEniCS Q&A source code anywhere to propose a pull request.

I'm not sure how to upgrade MathJax in the Q&A. Maybe @chris_richardson knows?

[Michal Habera]

This should be an issue of minutes. Just find "/qa/mathjax/" (or where it actually maps) folder and replace its content with the one in https://github.com/mathjax/MathJax/archive/master.zip

This will work, but I do not know if there is some internal way of how Q&A would like it to be done.

I'll take a look

Updated Mathjax to 2.7
