rename change_directory to directory_changed in event manager Attempt to be clearer that this action is a notification about a directory change that has happened, not a request to change the directory. * event-manager.h (interpreter_events::directory_changed, event_manager::directory_changed): Rename from change_directory. Change all uses. * qt-interpreter-events.h, qt-interpreter-events.cc (qt_interpreter_events::directory_changed, qt_interpreter_events::directory_changed_signal): Rename from change_directory and change_directory_signal. Change all uses. * main-window.cc (main_window::update_octave_directory): Rename from change_directory. Change all uses.
