Cleaned up the run script a bit. It's still focused on running Restolino
for Restolino development, so isn't a good example of how you'd run your
own app.
Changed the servlet API from "provided" to "compile" scope. Seems
sensible and helps with running Restolno on its own for framework
development.
Added basic 404 handling for file requests.
Added a toString method that summarises the resolved configuration.
Added a printout of the resolved configuration once everything is up and
running.
Improved startup messages.
