new test for xml serialization
getting jetty:run to work, but this is sort of pointless - really should be handled in the lux project since this project is all about the app server code, which has jetty embedded.
rev. 0.7.1
also includes support for integration tests via mvn using jetty:run, but this is really not the right thing
runs lux app server using code in this and the sibling lux project without needing to look in repo
