[Users] Add all geoserver layers automatically

[Andreas Hocevar]

Yes, you need to provide a complete capabilities url for the url parameter:

    http://localhost:8080/geoserver/wms?SERVICE=WMS&REQUEST=GetCapabilities

Also note that if your GeoServer is on the same host as your
application (http://localhost:8080/ in this case), you can use

    /geoesrver/wms?SERVICE=WMS&REQUEST=GetCapabilities

This will avoid cross domain scripting issues.

Andreas.
