Update documentation
Remove coffeescript and use plain Javascript.

I do not like the complexity Coffeescript adds. I want it to be as easy as
possible for people to contribute. Consequence is that the Javascript is now
still generated Coffeescript, but it doesn't look that bad.
Remove unused benchmark files
Remove big.html. This example has been merged into index.html.
Fix failing tests in IE9
Do not use filter method as IE <= 8 does not support it, instead use
jQuery.inArray and splice.
