Reformat Changes as perl CPAN::Changes::Spec



Hi,

I've reformatted your Changes file according to the spec in `CPAN::Changes::Spec`. I looked up missing dates at [BackPAN](http://backpan.perl.org/authors/id/T/TO/TOKUHIROM/).

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,
Sergey
