Tweaked Changes file and added github repo to metadata

Hi Brad,

I've tweaked the format of your Changes file, to satisfy CPAN::Changes::Spec:

 * Dates in ISO 8601 date format
 * blank line between header line and first release
 * Changed all tab characters to spaces (not required, but meant the file looked funny in [some places](http://changes.cpanhq.org/dist/Parse-Syslog-Line/2.3))

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 added `[GithubMeta]` to your dist.ini - this will add the github repo to the dist's metadata, so it will be listed on the sidebar in MetaCPAN, for example.

Cheers,
Neil

PS I'm doing this because I'm on a quest to help improve CPAN:
