                        PackagePreviewContentProvider.java
  Log:
  got rid of the working copies idea, and eliminated the model bridge as it was making things too complicated. package nodes now keep references to their parents and children, (just like delegates). there shouldn't be any need for synch as addChild/removeChild take care of all the details there. the way to create a package node that isn't attached to the model yet is:
  
  pkg = PackagesCore.createDetachedPackage(project, true);
  pkg.setXXX..
  PackagesCore.attach(pkg, monitor);
