Changes for version 1.03
- the Björn Again release
- This has been a looooong time coming, and I've only just managed to get off my arse and fix it thanks to Björn Tackmann.
- Fixed test 41 was incorrect.
- All other tests were correct, but as date math had changed, we needed to refactor the normalisation
- Updated DateTime requirement to 0.30 -- the new math
- DateTime::Format::Duration - Format and parse DateTime::Durations
