fix Changes to comply w/CPAN::Changes::Spec

Hi,

I've reformatted your Changes file according to the spec in `CPAN::Changes::Spec`. The date for the first release was missing, I got it from [BackPan](http://backpan.perl.org/).

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,
Sergey

PS: I'm doing this because I'm on a quest to help improve CPAN.
