Wish for auto-increment rendered image name.

[mgibeault]

I would find very useful a check box besides the "Output file" field that would add an auto-incremented number at the end of the saved image.
This way it would be very easy to save some quick tests renders without the 4 mouse-clicks to change the file name or filling the history palette.
It could also be an option to use a time stamp to auto-name renders (like "2015-02-25_11-05-34.jpg)

Thanks!

Yes, this would be great!
