feat(frame-grab.js) functional make_story method  #2

TODO:
- Come up with better algorithm for determining time for each frame.  Currently, if the user asks for 2 images to be generated, and the video is 1 minute long, the first image is generated at time 0, and the second at the 30 second mark.  A better story would include a frame from the 15 second mark, and perhaps another from the 45 second mark.

feat($fedex): remove frame rate requirement

It is not reasonable to require the frame rate in all cases.  In fact, it may be exceptionally difficult to determine the frame rate without the aid of a very knowledgeable user or a server in many cases.

feat($fedex): marginally better solid frame detection

Off-black frames (frames that appear black but are made up of varying shades of black) are not properly detected though.  Will need to adjust this algorithm to detect a frame made up of similar colors as "solid".

feat($fedex): more improvements to solid frame detection

Note: This is pretty awful code right now.  Refactoring is necessary after FedEx Day.
