Update of gh-pages and examples

[jesperronn]

Hi,

I was struggling with a code example in a jsfiddle, and suddently I realized the js file I pulled was 4 years old.

I pulled http://kpdecker.github.io/jsdiff/diff.js, which comes from gh-pages: https://github.com/kpdecker/jsdiff/tree/gh-pages

Do you plan updating this?

Done.

Awesome, Thanks!

BTW, I think you should add version number in the header of diff.js, but that's another story :)
