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

Hi Gerda,

I've reformatted your Changes file according to the spec in CPAN::Changes::Spec. This was mainly changing the dates to be in ISO 8601 date format. I also made the spacing consistent.

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:
