Weld Deployer not working with new JSF Deployer

I think this will require Weld Deployer changes, so assigning to Ales for now.

I've integrated the JSF Deployer into AS but now the Weld tests are failing. If you deploy a Weld app you will see:

18:58:51,956 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/weld-numberguess]] Exception sending context initialized event to listener
instance of class org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
: java.lang.NoClassDefFoundError: javax/faces/application/ApplicationFactory

The JSF deployer is much more selective about adding JSF to the classpath. It looks like JSF is probably trying to load org.jboss.weld.integration.webtier.jsf.WeldApplicationFactory that is defined in weld.deployer/lib-int/faces/META-INF/faces-config.xml. I think what happens is that this WeldApplicationFactory is loaded from weld.deployer/weld-jboss-int-webteir.jar. Then it references a JSF core class and it can't find it because the classloader for that doesn't see JSF.

The tricky part is that you can't just add JSF to the classloader for that jar. Each WAR can have a different JSF Implementation if it wants. So this sort of thing must be done for each individual deployment.
