Title: Toggle mirrored mode

I have implemented mirrored mode. I have a case, which may be quite common, when slides are projected from the back side of the screen, which is semi-transparent. Thus we need to mirror the presented image, to be read correctly on the front side.

That's why I created 'Toggle mirrored mode' triggerred by pressing 'm' keyboard. If you like it, please include it.
