Review request for Dolphin.


Repository: dolphin


Description
-------

The existing code suggests that the show filter bar action should be a
    KToggleAction.  DolphinViewContainer emits a showFilterBarChanged signal
    that is connected to DolphinMainWindow::updateFilterBarAction() to call
    setChecked() on the show filter bar action, which currently does nothing
    because the show filter bar action is not a checkable action.  I've
    changed the show filter bar action to a KToggleAction, and updated the
    code to make it function as a toggle as I believe it was intended.  If
    this was not the intention, then the existing code related to
    DolphinMainWindow::updateFilterBarAction() should be removed as they are
    not doing anything.
