[0.14.16] Error dialog box is behind gui.center

[MrDoomah]

So I have a mod that creates a large frame in gui.center on player creation, but any error dialog boxes appear behind this frame and are inaccessible.



Now you can't press 'ok' and have to force close factorio instead of just starting a new game.

Fixed for 0.14.16.
