Currently the onboard OSK is shown and hdden by starting and killing the process. Even the source code says "Not exactly a great solution". And indeed, there is a DBus method allowing to show and hide the OSK by sending

dbus-send --type=method_call --dest=org.onboard.Onboard /org/onboard/Onboard/Keyboard org.onboard.Onboard.Keyboard.Show
dbus-send --type=method_call --dest=org.onboard.Onboard /org/onboard/Onboard/Keyboard org.onboard.Onboard.Keyboard.Hide

As Qt offers a DBus interface, we should use this. So

Launch onboard only if it is not running.
Use DBus to show and hide the OSK.

For openSUSE builds, add a Recommends: onboard (stronger) or Suggests: onboard (weaker) to the spec file.
