RAT v3.0.3 release

RAT v3.0.3 was released on 3 November 1996. This was the first release in the RAT v3.0 series, which was the result of a significant effort to internally restructure and modularise the code, after Orion Hodson and I joined the project.

The final release in the RAT v3.0 series was RAT v3.0.35, released on 9 July 1999 (changelog).
