Select last visited folder when going up/back
This fixes a regression. When going up in the hierarchy of the file system (either by using the "up"-, the "back"-action or by using the UrlNavigator), the folder further down in the hierarchy the user is coming from is supposed to be selected.
The regression was introduced by ad5d3367. A lot of connections were changed there and at least one of them was wrong. The connections can be separated into GUI connections and internal ones. This commit makes it so the GUI stuff is connected to m_urlNavigatorConnected and everything else to m_urlNavigator.
