Comment:

 Ok, I kept thinking about the usefulness of the style and rule framework,
 and here I am finally with a patch, incremental to
 http://trac.openlayers.org/ticket/533. It makes minor changes to three
 classes:

 * OpenLayers.Layer.GeoRSS: new style property which will be passed to the
 marker, if set. Also parses the "category" tag in RSS 2

 * OpenLayers.Marker: new feature and style properties. Both will be
 destroyed in the destroy method, to avoid memory leaks by the circular
 reference between feature and marker. Also, if the style property is set,
 it will be parsed and the marker icon will be set to the externalGraphic
 property of the style.

 * OpenLayers.Feature: adds a reference to itself in the createMarker
 method. So now the marker knows about its feature, like geometries already
 do.

 I also modified the georss.html example to show the new feature, by using
 the newly added georss-category.xml example feed.
