GUI: when the config panel is open, and using keyboard shortcuts for frame-limiter (F4) or aspect-ratio (F6), reflect it at the GUI, but ONLY if there are no intermediate changes at the GUI (i.e., only if the "Apply" button is currently disabled). This would prevent re-applying obsolete values when clicking Apply/OK for for these two configs (after they were changed via KB while the GUI was open).

This is a very light infrastructure to allow some synchronization between KB shortcuts and the GUI. Currently only used for frame limiter and aspect ratio KB shortcuts. I wanted to also use it with frame-skipping (shift-F4), however, frame skipping GUI seem to have other issues which prevent it from properly reflecting KB modifications, so it's out for now.
