Check request param to recognize JSF 2 Ajax requests

Browse Source 
Previously we checked the "Faces-Request" header only.
Now we try to delegate the call to
PartialViewContext.isAjaxRequest() first. If a FacesContext
is unavailble for some reason we also check the
"javax.faces.partial.ajax" request parameter.
