Variables window not saving/reloading window position properly.

[kaydeeH]

When you get your monitor all set up the way you like it, close it, and reopen it, it always fails to open the variables window (no error, but the checkbox is not checked so it isn't open). If you open it manually by checking the box, its settings are lost and it opens using the settings for the mode window (they always directly overlap each other).

I'm not set up for branching this project and making a pull request, so my apologies there, but I do know the sources of the issue and the fixes. Looks like an old copy and paste issue that has slid under the radar...

In the mpfmon.py file, improperly references modes window:

self.toggle_variables_window_action = QAction('&Variables', self.device_window,
                                        statusTip='Show the variables window',
                                        triggered=self.toggle_mode_window) 

Also In the mpfmon.py file, missing a reference to the variables window entirely:

monitor_windows = {
            'devices': self.device_window,
            'pf': self.view,
            'modes': self.mode_window,
            'events': self.event_window,
            'inspector': self.inspector_window
        }

In variables.py, improperly references modes window:

        self.ui.move(self.mpfmon.local_settings.value('windows/modes/pos',
                                                   QPoint(1100, 200)))
        self.ui.resize(self.mpfmon.local_settings.value('windows/modes/size',
                                                     QSize(300, 240)))

Found in MPF-Monitor 0.57.1. Fixing those got it working as expected for me. Thanks!
