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

Hi John,

I've reformatted your Changes file according to the spec in CPAN::Changes::Spec. This just needed a change in the way dates are formatted.

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
