Reformat change log as per CPAN::Changes::Spec

Hi,

I've reformatted your Changes file according to the spec in `CPAN::Changes::Spec`. The date for the first release was missing, I got it from [BackPan](http://backpan.perl.org/).

Here's more [clear diff](https://github.com/sergeyromanov/list-objects-withutils/commit/f2e0c9baaacdc2231c8716d781508c106e47eff1?w=1).

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

PS: I'm doing this because I'm on a quest to help improve CPAN. Read more about [the quest](http://questhub.io/realm/perl/quest/51f0337718ba7d3959000086) at [Questhub](http://questhub.io).
If you decide to update your other dists, feel free to log them in comments on the quest -- every dist helps!
