Change web.xml setup to use WebServlet annotations. Solves problem of having the correct web.xml when combining Servlets via Maven profiles. Works only with Servlet 3. For Servlet 2 you still need to patch your own set of Servlets into web-2.4.xml. You can still override Servlet mappings in web.xml if you want (watch out for servlet-name).
