Upgraded maven-jetty-plugin version to fix all the examples that used the user agent examples, which are now web fragments.  This change required a minor media type matching enhancement in the Atom and HAL providers.  Plus this change also delivers a working CORS example.
Fix the useragent-odata-html example (it did not include any of the web fragment resources) and add a 'Load' button that can load any OData service that has enabled CORS.
Fix the packaging of the other web fragment base user agent examples.
