This is the start for adding proper support for keyboard layouts. If we have a configuration in kxkbrc the keymap is generated from that information. This allows to have different layouts and also layout switching is working (though not yet passed to Wayland clients properly). Not yet working is the global shortcut for layout switching and reconfiguring the layouts.
