hgweb: refactor graph customization javascript

- Avoid flipping lineWidth state around the edge() call, pass it to the
  function instead.
- Pass the line width and color appended to the other parameters instead of in
  a dictionary. The javascript code is simpler, no need to check for all
  containers existence, and the JSON output is smaller.
- Reindent setColor() comments and fix code spacing.
