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

Hi,

I've reformatted your Changes file according to the spec in CPAN::Changes::Spec - this involved:

  * Reversed the order so most recent release is listed first
  * Not all the releases had dates against them, so I looked them up on BackPAN
  * Put all dates in ISO 8601 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:
