get master working with jboss 7.1.1:

- delete excluded jars in build.xml because jboss has some Class Not Found exceptions
- change js in web/login.html, web/login.jsp beacuse the language var is empty sometimes
- change default dir from "" to "images" in web/js/lib/themeswitchertool.js
- fix getResource for oviyam2 config in XMLFileHandler.java
