- Add support for Alpah Release Notes on .f version of 6000 Unity.

- Fix an issue with the alpha release notes website where the list included changes of the closest  version, even though the user wants a strict diff.
Thisi is done by adding a string list representation of the updatelist so as to be able to use Tools.FindNeatestVersion on that.
