Adding two wps process services and a dashboard UI that uses them

Added an interface for getting a connection to the database. Added the two existing implementations, JNDI and String/Property based.
Set up a base class for the services. This currently requires/expects Postgres as the database and will need be refactored to be agnostic.
Added on the list service at /list that returns the data as JSON.
Added on the report service at /report that returns the data as JSON.
Added on a UI JSP at /dashboard that exercises both services and displays them as HTML
