    js: Copy-to-clipboard support
    
    Now using the browser's "copy" operation while the focus is in the
    puzzle will copy the puzzle state to the clipboard.  Browsers seem to
    have odd ideas about whate element to target with the "copy" event:
    Firefox targets the parent of the <canvas> while Chromium targets the
    <body>.  To cope with these and possible future weirdness I attach the
    event handler to the document and then look to see if it's plausibly
    related to the canvas.
    
    Arguably we might want to handle a wider range of "copy" events, maybe
    any where the selection isn't empty.  I'm not sure, though, so we'll
    start with the minimal change.
