Add DBus protocol to virtual keyboard

Browse source 
Summary:
This change adds a DBus API to query whether the virtual keyboard is
currently enabled and provides DBus methods to request that the virtual
keyboard gets enabled/disabled. This is useful for e.g. providing a
Plasmoid or for convertables where the tablet mode needs to be enabled.
