Fixes: NB#79791: Cannot set focus to Master volume using stylus

	* src/hildon-volumebar.c
	* src/hildon-vvolumebar.c
	* src/hildon-hvolumebar.c (init): remove UNSET_FLAGS(CAN_FOCUS) so
	the widget becomes focussable at all.

	* src/hildon-volumebar.c: implement GtkWidget::grab_focus() and
	set the focus to wither the mute button or the volumebar.

	Remove own "can-focus" property and instead listen to
	notify::can-focus in order to update the widget's state.

	Implement GtkWidget::focus() and make sure we can also *leave* the
	widget, not only enter it, depending on volumebar orientation and
	requested focus direction.

	Clean up set_mute() to cooperate nicely with all the above.
