Updated Changes file and Build.PL

Hi,

I updated your Changes file, making it conform to CPAN::Changes::Spec in the process:

 * added all releases, with dates taken from [BackPAN](http://backpan.perl.org/authors/id/N/NI/NICWOLFF/)
 * added bullets for each release, taken from git log

I also added your github repo to Build.PL's meta_merge resources, so it will appear in the dist's metadata. This means it will appear on the sidebar in MetaCPAN, for example.

Cheers,
Neil

PS I'm doing this because I'm on a [quest](http://questhub.io/realm/perl/quest/51f0337718ba7d3959000086) to help improve CPAN.
