widget.get_abs_rect is not quite right

Here is a fix that we use instead of the built in widget method. The one built 
into widget wasn't returning quite the right size.

def get_real_abs_rect(widget):
    """Get the absolute position and dimensions of a widget on the screen.                                                                                                          
    (Does what gui.Widget.get_abs_rect() claims to do, but actually does it                                                                                                         
    correctly.)"""
