Fix bug where KPart did not emit setWindowCaption() signal until it gained focus.  Call controllerChanged() in ViewManager::createController() so that an activeViewChanged() signal is emitted when the first controller in the view manager is created.  Fix ViewManager::controllerChanged() to only emit an activeViewChanged() signal if the new and previous controllers are different.  Remove the checks for this from the MainWindow and Part slots connected to this signal.
