Subject: [PATCH] keyboard: Implement more of the wayland caribou adapter

Have it notify properly of changes to the current input source, as
well as exposing those in get_groups().

The support for virtual keyboard events has been replaced by
ClutterVirtualInputDevice, which can be thought of as the equivalent
to the XTEST devices in X11.
