fix: [1/2] Keyboard Layout applet doesn't follow actual layout switching

Andrey Butirskyrequested to merge
(removed):keyboard_layout_plasmoid into master

We need to emit DBus signal on every layout change - explicit(keyboard shortcut, layout applet click) and implicit(focus window with different layout). Otherwise, external layout applet might be not updated.
