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

Hi,

I've changed your changelog to confirm to the spec in CPAN::Changes::Spec:

  * renamed from CHANGELOG to Changes
  * reformatted dates and added version numbers (found from backpan)

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:
