    files-view: added alt+return shortcut for properties
    
    With nautilus 3.16 the properties shortcut was changed from
    alt+return to ctrl+i.
    
    alt+return is a known shortcut in other applications for showing
    file properties, so it was proposed to add alt+enter and altgr+enter
    as shortcuts in bug 662081.
    
    nautilus_application_add_accelerator() does not accept multiple shortcuts
    per action, so I used gtk_application_set_accels_for_action() and bound
    view.properties to the array open_properties.
    Also the additional shortcut was added to the shortcuts overview.
    Unfortunately, I couldn't find a reliable way to bind altgr for the
    shortcut, as modifiers are dependend on the X server mapping.
