1.  Deprecate (or just remove) the Style event notification code; it is broken unused and a bad idea
2. Upgrade GeoTools style classes to match SE 1.1 in place via a proposal
3. Rename org.opengis.sld to org.opengis.stlye and update with the interfaces matching GeoTools definitions (ie SE 1.1)
   • Go over SE 1.1 specification updating javadocs and methods as needed
4. Throw out GeoAPI org.opengis.feature.style package (it was working on graphic and is no longer needed)
5. Release a milestone GeoAPI jar
6. Change the GeoTools interfaces to extend the GeoAPI interfaces via a proposal (this is now possible with type narrowing!)
