Title: Better filtering of servlet-api JARs when writing uberwar

In uberwar, check for the presence of the javax.servlet.Servlet class to filter out servlet-api jars instead of relying on the "servlet-api-" filename prefix. The latest Jetty includes a servlet-api dependency that doesn't follow this naming convention, and Tomcat rejects the resulting WAR built from projects with a ring-jetty-adapter dependency.
