AJAX partial page submit (PPS) works now for containers. I've changed
the iteration algorithm to recursively iterate through the tree in
j4fry_common.js. As soon as a PPS node is found all of its children as
submitted with the old algorithm. The id of the PPS node is submitted
so the listener finds it when decoding, validating and updating the
model. I had to add the jsf keyword "javax.faces.ViewState" to the
list in the script. There are two new functions addNodes and
addField.
