Responsive design and a new utility

A bit late to the game but you can now use all of the utilities available on abunchofutils.com on small-screen devices thanks to a responsive design.

Some of the utility interfaces are quite complex so this wasn't straight-forward for all of them and it means some more advanced features are not available on every device. Rather than create a cluttered interface we display only the essential features on smaller screens and this seems to work quite well.

In other news, we added a new utility recently. The new Word density counter utility simply shows a summary of the occurence of distinct words within a given text sample.
