Double click fixes

Made some changes, but didn't edit all files.
Didn't edit the version in lib/ and also didn't minify the script. Sorry in advance.
Also made a change to the README file to include a demo page. You will probably have to checkout: https://help.github.com/articles/creating-project-pages-manually
I've already set-up a gh-pages branch, will also see if I can push that one.
