This patch adds a GShortcut class. Each GAction can have a GShortcut which will cause the event loop to listen for that key combination app-globally and activate the event in case it's pressed. The shortcut will also be displayed when the action is added to a menu. Use this to hook up Alt+Up with the "open parent directory" action in the FileManager app. :^)
