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

Hi Gabor,

I've tweaked your Changes file:

* dropped leading 'v' from versions
* changed dates to ISO 8601 date format
* Added a header line identifying the file and module

You know the [background](http://questhub.io/realm/perl/quest/51f0337718ba7d3959000086) :-)
You're number 188.

Cheers,
