Make more elements from web.xml available in WebXml

[GoogleCodeExporter]

org.omnifaces.config.WebXml currently provides access to several, but not all, 
element from web.xml that the current versions of the Servlet API do not 
provide access to.

It would be nice to implement the yet missing (useful) elements, such as 
security-constraint and welcome-file-list.

Some thought should be given whether complex elements like data-source are also 
needed (probably not, and this one is extra complex since it has a mirroring 
annotation).

For security-constraints, it might be handy to pair this with some utility 
methods such as hasUserAccessToUrl().

TODO: utility methods. I don't think that WebXml is the right place for that. A 
separate utility class like Users or Roles is a better suit.

Improved #getSecurityConstraints() and added #isAccessAllowed(url,role). I've 
put the method on WebXml anyway.
