When in Editing mode, the overview window no longer shows vertex mark… 
…ers. It used to, which generally made it overcrowded. This commit now only shows the vertex markers on the main canvas. In theory, this should also mean that the map composer window also doesn't show vertex markers any more (which should be a good thing), though I haven't tested it.
