Experimental option $wgMathUseMathJax to have Extension:Math load things via MathJax.

Browse source 
If enabled, by default loads MathJax from a CDN and forces all equations through MathJax when JavaScript is available -- the image or source form gets used only as <noscript> fallback.

This has a couple of problems for us:
* if scripts are missing -- such as when viewed via MobileFrontend -- you end up with no math at all, as the <script type="math/tex"> bits get ignored but the <noscript> still hides the images.
* while MathJax is loading things, blank spots on the page may appear and stuff jumps around
* if loading new text in via ajax, it doesn't trigger there

Also using some fairly default config, no idea how appropriate it is. Hoping to get some insight from Nageh who's done some of the MathJax work on Wikipedia so far - <https://en.wikipedia.org/wiki/User_talk:Nageh#MathJax_integration_into_stock_MediaWiki>
