* added stroke, fill and graphic symbolizer properties (all boolean) to

Browse Source 
control whether or not to render a stroke, fill and graphic.
 * added a defaultsPerSymbolizer property to OpenLayers.Style to allow 
for extending incomplete symbolizers with defaults for stroke, fill or 
graphic. This also makes Format.SLD read/write round trips possible 
without modifying empty or incomplete <Stroke/>, <Fill/> and <Graphic/> 
constructs. r=tschaub (closes #1876)
