This patch enables basic drag&drop between applications. You initiate a drag by creating a GDragOperation object and calling exec() on it. This creates a nested event loop in the calling program that only returns once the drag operation has ended. On the receiving side, you get a call to GWidget::drop_event() with a GDropEvent containing information about the dropped data. The only data passed right now is a piece of text that's also used to visually indicate that a drag is happening (by showing the text in a little box that follows the mouse cursor around.) There are things to fix here, but we're off to a nice start. :^)
