patch for DynamicURI to add JS-events

[Marc Lustig <ma...@marclustig.com>]

This is my patch. It contains only 1 tiny method that returns the
org.apache.ecs.html.A instead of the String. You are then free to use any of
the org.apache.ecs.html.A-methods to add stuff to your URI before you
convert it to String.

It goes like this:

   DynamicJsURI uri = new DynamicJsURI();
   uri.useDynamicURI-methods
   org.apache.ecs.html.A a = uri.getEcsA(text);
   a.setOnClick("aMethod()");
   String uri = a.toString();
