Reformatted Changes file as per CPAN::Changes::Spec

Hi Mike,

I've reformatted your Changes file according to the spec in CPAN::Changes::Spec

 * Added a missing date for 0.03
 * Put all release dates in ISO 8601 date format

Following this format means that various tools can more easily process your distribution automatically.

You can find out more about this at Brian Cassidy's [CPAN::Changes Kwalitee Service](http://changes.cpanhq.org), which is where I saw your module listed :-)

Cheers,
Neil

PS I'm doing this because I'm on a quest to help improve CPAN:
