Need welcome page at http://localhost:8080/

Browsing to http://localhost:8080/ gives a 404 error. It should at least present a minimal welcome page to reassure new users that the server is functional. Ideally, this page should give quickstart instructions for configuration, deployment, accessing the management console, etc. Links to example apps and instructions on where to find their underlying code would also be helpful.

Once this is done, the README file should be updated to de-emphasize the debug console, since users will no longer need to install that to verify that the server is running. (And unless they're debugging the server itself, it will probably not be a terribly helpful thing to do.)
