commit e7f2144e38c02f6aeba7b563e8bc1fb195616477

    Move slots from NautilusWindow to NautilusWindowPane
    
    A window does not hold lists of slots anymore, but lists of panes, which
    in turn hold lists of slots, making a slot effectively a layer between
    a window and a slot. Much of the remaining part of the patch is
    simply replacing "window->details->active_slot" with
    "window->details->active_pane->active_slot" and similar changes. Commits
    to move corresponding parts of the logic out of the window into the pane
    are to follow.
