* ScreenCornerSelector is now a BControl and fully keyboard navigable.

* simplified drawing a bit, and got rid of those scary scale*() stuff (which also
  results in better looks). The monitor now looks like the one in Screen; I think
  it should either be a very reduced form or a very detailed form, but anything
  in between often looks just odd.
* It now also listens to B_MOUSE_DOWN incl. mouse tracking, not only to B_MOUSE_UP.
* Less flickering on state changes (and focus change).
* Loading settings no longer overwrites defaults missing from the settings.
* Renamed ScreenSaverSettings::GetBlankCorner() to BlankCorner(),
  LoadSettings() to Load(), GetState() to GetModuleState(), ....
* Some more cleanup.
