Enhance globally the skinnability of the application by:
1. Creating separate CSS files for each browser and load each CSS file depending on the requesting browser, create multiple css file to handle differences among browsers. e.g. default-ie6.css, default-ie7.css, default-opera.css, default-ff2.css, etc...
2. Create separate CSS files for each JSF component, this will provide better styling of the component.
3. Remove all unused css classes and identities
4. Remove all inline CSS 

This could be enhanced furthermore to JS as well, for now we need to schedule a time to do a complete CSS cleanup of the app.
