CRS changes for revisions 28480:28481

The functionality and javadoc of this method have been fully rewritten. SIS puts this functionality in a different class (IdentifiedObject), uses a different method name (getIdentifierOrName), more generic signature (accept any IdentifiedObject instance), implements a different algorithm which looks for identifiers first before to fallback on name, and uses a more reliable formatting code than toString().
