Log would be nice to have for output of the waterfall #2

Hi, it would be great to have a possibility to log the waterfall output to an jpeg file, for a given time ( 3h, 6h,12h ?)

That file could have a place in the img folder and it would be nice if that file could be viewed from the remote computer too.

In the latest commit c000506, pressing 'd' key will download the current waterfall snapshot. Timestamping has some font scaling issues. The frequency axis needs to be brought in.

For continuous logging, fps can to be set to 1 or 5, waterfall window maximised and the plot captured when the screen is full. Multiple images then needs to be stitched. Capturing can be automated by calling the downloadWFImage() function - based on the time it takes for the screen to fill up.
