Title: Customizable LegendImage

With this pull request, the aim is to let the developers customize the way they display the legend images for each item of a WMSLegend.
In the proposed patch, I changed the LegendPanel example to show layers with several classes (rules) and LegendImage customization shows how to add a translated label for each layerParam in the WMS layer.
Please review.
