[Users] UrlLegend

[florent.gravin at bluecham.net]

hi, thks for reply,

I've already the param preferredTypes: ['gx_urllegend'], but it's not the
point i think... because when the legendPanel creates the layerLegend, the
layerRecord "legendURL" haven't been set yet.. so, the only type it finds
on creation is gx_wmslegend

i need to specify it's an URL legend BEFORE the legendPanel have been
triggered to create and add the new LegendLayer
