MathJax (LaTeX) upgraded to 2.0

MathJax has been upgraded to 2.0 today. Some members appeared to have problems due to cache conflicts. I've changed the CDN address and now it should be working smoothly. Take some time to look over "what is new". I'm sure you'll find some interesting new features.

I am regularly in contact with the devs, please report any bugs or feature requests. [Broken]

I am not sure how it was in the past, but \vec doesn't work correctly with Chrome nor Opera.

[tex]\vec x[/tex]

(in Chrome it is even worse - it displays just a square instead of a misplaced arrow)
