Fix typos / style
Changed 'Example Web Service' link in README.md

Old location that the link pointed to no longer exists on the master branch of the trapperkeeper-webserver-jetty9 project.  Updated the link to point to the base directory of the Ring example in the trapperkeeper-webserver-jetty9 project.
