[Trinidad] New API for UIXEditableValueTemplate

[Ji Kim]

Hi,

This thread is to discuss JIRA 
[https://issues.apache.org/jira/browse/TRINIDAD-2459] which is to add 
two new APIs of

public void addValueUpdatedListener(ValueUpdatedListener listener)
{
  super.addFacesListener (listener);
}

public void removeValueUpdatedChangeListener(ValueUpdatedListener listener)
{
  super.removeFacesListener (listener);
}

This is to allow component's and etcetera to add NEWLY added 
ValueUpdatedListener listener to the component where ValueUpdatedEvent 
is queued within the updateModel method/phase.

Thanks!
