Display amount of samples in Render Info, when render with Time Limit

While rendering with a time limit is pretty handy for quick previews, it would also be nice to know how many samples the render did when it's finished within this time limit (single render). Currently I think there's no way to see this (besides monitoring the render process when finishing).

In the mockup I used a Time Limit of 20 seconds, and Blender rendered 1234 samples in this time (out of the 4096 that are originaly set), added this to the info bar with render data.
