Issue description: Menu bar width is not updated when changing from DE locale to EN locale

Steps to reproduce:

1. Switch to DE locale
2. Switch to EN locale and get

Reason: UIMenubar.inst.menubarw is not updated in Translator.hx in

for (ui in uis) {
	ui.ops.font = f;
	ui.setScale(ui.ops.scaleFactor);
}

A possible fix would be to call BoxPreferences.setScale(); but this doesn't seem to be a good fix for me. I think it would be best to refactor the scaling behavior such that there is one method to call from all locations. But again this is clearly non priority.
