[Users] Legend tree custom image URL

[Hugo]

Hi guys,

I've made a small change to the WmsLegend class and now it works perfectly.
I've just added the following code inside the getLegendUrl method (at line
145):

if (rec.get('legendURL') != ''){
     url = rec.get('legendURL');
}

Obviously this assumes that if legendURL is different than an empty strig,
it will override the url returned by the styles definition.

Cheers,
