Put the streamSearchBean in the view scope.
Integrated the Omnifaces utility library for JSF 2 to support CDI in the
view scope (NPE with Tomee 1.6.0/MyFaces 2.1.13).
Note: we can get rid of Omnifaces if we migrate to MyFaces 2.2.0 (by
replacing the jars in the Tomee lib directory): it works well but it
ends up with bad UI rendering.
