[Pharo-project] Enhancement - version history to include class and method renames

Since <Versions> shows both the class name and method name, it would be useful to have class and method renames to have that show up in the version history. Use case: 1. PersonA creates a ClassA and methodA. <Versions> shows the author of ClassA>methodA as PersonA. 2. PersonB renames classA to classB. <Versions> shows the author of ClassB>methodA as PersonA. Where as I think the guilty party should show as PersonB. cheers -ben
