Mode 1759 Added two new ModeShape examples: Tomcat & Spring

* one example uses ModeShape + CDI + JSF to generate a standalone web application that should be deployed in Tomcat 7 (or newer). The reason for the specific version of Tomcat (or any web server for that matter) is that the necessary JAR combination to make JSF  work differs between servers

* the other example uses ModeShape + Spring (Context + WebMVC) + Atomikos to generate a standalone web application that should work in pretty much any web server.
