Fixed 404 for ZeroClipboard.swf on gh-pages

* Updated ZeroClipboard to use new v2 init syntax
* ZeroClipboard doesn't allow you to use relative URLs when setting the path to the `.swf` in the config. This caused problems as the development environment is at the rooter of the URL, i.e. /js/zeroclipboard, but on live it is '/inuit.css-kitchensink/js/zeroclipboard'
