No HTML representation for the about display.

Within the pdfbox-rest-application project the ApplicationResource class has an about method that returns XML or JSON but not and HTML representation, this can be seen at http://preflight.verapdf.org/about as XML. The client() method in the same class renders the HTML page at http://preflight.verapdf.org. It'd be nice to have an HTML view for the about page.

This will also require a mustache template, the existing template for the home page is called restclient.mustache. You could replicate this in full with the appropriate about template but there's bonus point ;) for using mustache partials to separate out the common parts of the page, e.g. the header, the google analytics and the javascript/css includes.
