Fix some wierdness with the debug menus...

Set the current viewport back to NULL after the list is finished drawing, Screens 
should be setting it before they start drawing so this probably only effects the debug menus.
Also change how the statusbars are handled there to make things easier. (this change also forces the bars back on (if enabled) in the simple list widget.. hopefully this doesnt cause problems later)
