Currently the SelectAction will only handle the left and middle mouse buttons (MouseEvent.Button1 && MouseEvent.Button2).  A lot of applications the user 
would like to be able to right click on a widget and select the widget as well as bring up the context menu.  

So the SelectAction should respond to the MouseEvent.BUTTON2 event, and select the associated widget, and then allow other actions to handle the event 
as well.  

Proposed changes to make this behavior happen.  The proposed changes would be backward compatible with current implementation.

1) A new constructor should take a SelectProvider as well as a boolean to determine if the right mouse button should be handled.
2) the mousePressed method should look like this:
   if (event.getButton ()  ==  MouseEvent.BUTTON1  ||  event.getButton () == MouseEvent.BUTTON2) {
    ... // Same as currently implemented
   }
   else if(event.getButton() == MouseEvent.BUTTON3)
   {
      provider.select (widget, localLocation, invertSelection);
      return State.CHAIN_ONLY;
   }
3) The ActionFactory should have a new createSelectAction method that takes a SelectProvider and boolean.  The boolean would specify if the right button 
should be handled.
