Format.WMSGetFeatureInfo: parse geometry if present for msGMLOutput

[bartvde]

patch implementing geometry node parsing for Mapserver

[elemoine]

Bart, could we avoid creating a new Format.GML object for each feature by caching the first created format:

parseGeometry: function(node) {
    // we need to use the old Format.GML parser since we do not know the  
    // geometry name
    if(!this.gmlFormat) {
        this.gmlFormat = new OpenLayers.Format.GML();
    }
    var feature = this.gmlFormat.parseFeature(node); 
    var geometry = null; 
    if(feature && feature.geometry) { 
        geometry = feature.geometry.clone(); 
        feature.destroy(); 
    } 
    return geometry; 
},

Hi Eric, sure makes sense, I'll adapt the patch.
