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

Hi Moshe,

I've tweaked the formatting of your Changes file to conform to CPAN::Changes::Spec:

  * Changed some of the dates to ISO date format (that weren't already in it)
  * Consistent formatting of bullets / spacing to match the most common style you were using

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:
