[Users] Change order of base layers

[Andreas Hocevar]

Hey,

all you have to do is configure your OpenLayers.Map with {allOverlays: false}.

Also, note that you don't need to create a LayerStore if you're working with a GeoExt.MapPanel. Just configure the MapPanel's layers property with the result from createLayers.

So your mapPanel configuration could look like this:

{
    xtype: "gx_mappanel",
    map: {allOverlays: false},
    layers: createLayers()
}

Regards,
Andreas.
