Just committed an Ajax Listener component

[Travis Reeder]

Basicallys lets a component listen for events on another component, all via ajax. 

Sample usage on inputAjax.jsp.

     <s:outputText value="#{inputAjaxBean.waitingText2}">
        <s:listener on="formText2"/>
    </s:outputText>

Only works with the sandbox OutputText right now, but after I get some feedback and discussion on it, I figure it would be nice to have across the board.  It's a bit more functional than the ADF partial triggers because it *will* be able to support different event types (onChange currently) and different actions (update currently, but will could support other actions including calling an arbitrary _javascript_).

Any feedback appreciated.  And thoughts about applying this to all MyFaces components?
