This patch switches the cdn to upstream and removes a lot of stuff that I
believe mathjax will figure out on it own.  I'm no mathjax or webs export,
though.  Notably, mathml stuff is gone.

OTOH, I added some display options, which I believe one might care about.
If more "user-sensible" options exists I can add them.

It would be good if someone who knows MathJax better could reviews this.
