RT-25559 Allow event handlers to come from the namespace

[Milan Kubec]

Hello,
mentioned issue suggests to search also FXMLLoader namespace for event
handlers. That's good idea but the open question is how to prefix the
name of the event handler - either with # as event handler method or
with $ as reference to Namespace, both are correct in some sense.

The fxml code would look like this (no controller is defined):

<?import javafx.fxml.Widget?>

<Widget onNameChange="#manualAction"/>

or

<Widget onNameChange="$manualAction"/>

For reference: http://javafx-jira.kenai.com/browse/RT-25559

Thanks

  Milan
