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

Hi Whitney,

I've updated your Changes file to follow the format defined in CPAN::Changes::Spec:

  * Added a header line identifying the file / module
  * Changed dates to the 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:
