Printing MathJax formulae about decktape HOT 3 CLOSED

I've just pushed @eb0e3c63c91484b9d350175d19bd07026e68a924 which waits for the End MathJax StartupHook before exporting the slides.

Unfortunately, the type setting is still incorrect in the example that I've tested so far (the math.html example from reveal.js source). Even the example from https://gist.github.com/pkra/52391c345ae48613e5e0 fails to render properly with the latest version of PhantomJS. So I suspect this is more a PhantomJS issue with MathJax typeset functionality though maybe you could give that first commit a try to have your opinion on this.

hmm, the problem was in lack of my knowledge reading MathJax docs. one more option to MathJax.Hub.Config fixes that problem:

"HTML-CSS": { availableFonts: ["TeX"] }

so probably without waiting till End we could use decktape just increasing timeout in --pause option.
Upside of this investigation are that

• now I can remove that pause
• I've learned to use KaTeX that works also well with remark & decktape (and is know to be a bit faster)
