Fixing Jetty and Tomcat profiles & project to have examples run in command line

mvn -Ptomcat clean tomcat7:run and vn -Pjetty clean jetty:run work in command line.
Produced war (for instance with vn -Ptomcat clean package) still coantins a lot of garbage. Didnt't tried to deploy it. We should discuss the organization of the quickstart
(expecially overlay approach) first.
