Fixed an issue where the Tomcat Managed container configuration validated server.xml from CATALINA_HOME instead of CATALINA_BASE.
Corrected Servlet spec versions.
DRY'd up test code.
Updated to the latest JBoss coding conventions per https://github.com/jboss/ide-config/blob/master/README.md.
Improved Cargo configuration to stop Tomcat after each remote container integration test run.  Switched the managed containers to use Cargo instead of Ant tasks for Tomcat download and configuration.
