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

Hi,

I've reformatted your Changes file according to the spec in CPAN::Changes::Spec. This was basically changing the dates to 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:
