We have a much faster interactive image map!

* Image for highlighting rivers in link list instead of CSS manipulation.
* Better event handling.
* No more hover delay.

Some problems still exist:
* Sometime when switching the module to 'MINFO' the highlighted river on the
  image map is not unhighlighted.
* The loop to unhighlight rivers when switching modules is called for every
  river.
