Analysis GUI improvements for more intuitive use

[arnicholson]

These are a few thoughts I've had about changes that would make the GUI Analysis easier to use.

• The video preview should have timestamps so that you can track where you are in the video. The scrollbar is only a rough approximation, and especially if there are no errors you can't really tell with any accuracy.

• Clicking a point in the graph should take you to that point in the video.

• Similarly to the above, selecting a point in the graph or the video should take you to the nearest error in the frame table.

• I'd also like to call out Distorted sound in Analysis window #672 as it is still happening and would also be very helpful in improving the intuitiveness and usability of the GUI Analysis

If any of these don't make sense or aren't viable for any reason, I'd love to know why! They make sense to me but I know that doesn't mean they'll make sense in actual application.
