Development

Added Jetty support for Zuul using http://uguptablog.blogspot.co.uk/2012/09/embedded-jetty-executable-war-with.html as a template. 
Changes:
* Update pom to package the war file as an executable using Jetty so it can be run as java -jar zuul.war
* Moved taglibs to support the location that Jetty expects them to be.
* Changed Spring application context to resolve the zuul-data-config.properties and ldap.properties from a file location rather than the classpath when running using Jetty.Still defaults to classpath when run as the war file within Tomcat.
