nitpicker focus

Hi Boris,

I had to solved this exact problem in the Sculpt scenario where the
control panel "Leitzentrale" should always have the keyboard focus while
activated. Otherwise, the regular nitpicker focus policy should be in
place. I hope that my solution works equally well for your scenario:

Please have a look at the combination of the 'nit_user_focus' and
'nit_focus' components in the sculpt.run script [1]. The former captures
the state of the regular nitpicker focus. The latter overrides the
former whenever the Leitzentrale is enabled.
