* new convenience method addUniqueValueRules in OL.!StyleMap. This can actually be used to achieve what I was trying to show in the example of this ticket's description.
* some refactoring of OL.Style to remove duplicate code (with tests)
* a new example showing how to add a "unique value" legend to a point layer using the new addUniqueValueRules method
* Rule.symbolizer can now also be just a symbolizer, instead of a hash of symbolizers keyed by "Point", "Line", "Polygon". This will make things even simpler (as can be seen in the styles-unique.html example)
