Popup menu

If you click the right mouse button in the directory listing panel, a popup menu will be shown. Its content depends on whether it is a local (first menu) or remote (second menu) directory listing. Particular commands in these menus are the same as in the application main menu. The only added item is "Sort by", which allows you to choose, which criteria will be used for sorting the directory listing (i.e. by name, date or size).
