r9759: Create some wrappers for QxWidget.  This gives us some pre-fabbed
windows, which set size and positioning.

To use:

var myWin = new Window.large("Some Window Title");
var myWin = new Window.standard("Some Window Title");
var myWin = new Window.small("Some Window Title");

You can omit the title if you don't need one.  Also,
var myWin = new Window();  will give you the random
positioning and no predetermined sizing.
