Dist enhancements

Hi,

I've reformatted your Changes file according to the spec defined in CPAN::Changes::Spec.

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 :-)

I also add a link to the repo into Makefile.PL, so it would be easily discoverable from MetaCPAN.
