Best solution: the code for going to the new slide should be in the view class,
not in the document class. Then the other views wouldn't be affected.
This is the cleanest solution, but I'm not sure how it works with the undo/redo problem.
You would still need an "active view" hack there.

Yeah, so indeed finding the "current view" sounds necessary, at least from 
within the command itself. You could cast the app's activeWindow to a KoMainWindow
and use rootView(), but this is far from clean (and breaks with embedded documents).
Might also break in koshell.

You could also simply set the current view somewhere while [un]executing commands
(e.g. in the command-history-derived class). I would find this cleaner.
In that case it would be simply about storing "this" from KoView code, no casts and
hierarchy navigation needed.
