ISO, shutter speed, f-number and focal lenght always on screen (in navigator)

[Alexander Korolev]

Hello!

I would like to have ISO, shutter speed, f-number and focal length values always on the screen in the editor, but in non-obtrusive way. I find quick info panel too obtrusive and inconvenient to use. I tried to add a line of text with this info to the navigator panel - two screenshots and patch attached. I kept it very simple (simple formatting, no other info like camera/lens model, etc.) and I like how it looks, but critique is welcomed.

I also changed formatting a bit for exposure compensation to show plus sign for positive values, as I find it more informative.

I used this particular order of values (iso, ss, f-number, focal length) because I find it more informative as well, even though it is not consistent with order used in other places (e.g. thumbnails tooltip or quick info panel).

If it is undesirable to consume vertical space, then I think we could compress width/height and x/y lines into one line.

I tried to put x y coordinates and width x height on the same line, and I think it looks better. Added another screenshot (same_line_for_xy_and_wh.jpg) and new complete patch (mypatch_2.patch).
