Comment (by tnolte):

 I've made some considerable changes to the LoadScaleRanges script as it
 was discovered that using the $_SESSION proved to be unreliable. Used the
 session and map name to make a direct read to the session map file(s).
 Also copied the "scale_ranges" building process from LoadMap directly into
 the LoadScaleRanges. This fixed the issue of the legend icons not being
 built correctly. I also made some changes to the Legend.js widget script
 to account for the as yet finished process of using just the sprite image.
 After loading up the map Legend updates were happening the old way but the
 background image positioning wasn't being reset back to '0px 0px' which
 caused the Legend icons not to show up. Will either come back to this and
 complete the changes to just use the sprite image or defer to Paul to
 finish that section up.
