Provide more information in page info notification

[MarkoD2K]

Shift+I in in fullscreen only is giving small tooltip with page no.

But will be very good if little more useful data is added also. Like file name, current image file name and image bytes (if 2 pages then data about 2 images).

I deleted the comments because this is not the place for such discussion.

I didn't close this request which means that if I get to implementing it, it'll be something close to what is requested (showing file name, size etc. when applicable).
