Reformatted Changes and added [GithubMeta] to dist.ini

Hi,

I've reformatted your Changes file to conform to CPAN::Changes::Spec

 * Added dates for all releases (got them from backpan)
 * It looks like 0.040 wasn't released, as I couldn't find it on backpan, so I put "not released" against it. If you have a date for that, you could update it.

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 :-)

Note, the version of CPAN::Changes::Spec running at that site doesn't yet understand "not released", but it's going to be updated soon.

Cheers,
Neil
