[Users] UrlLegend

[bartvde at osgis.nl]

The sequence should not matter, an event will be fired and the legend
should update.

See also the legendpanel example:

layerRec0.set("legendURL", otherUrl)

the legend image changes in this case.

Otherwise, please show us a minimal example which we can use to reproduce.

Best regards,
Bart
