Update and rename CHANGES to Changes

Hi,

I've reformatted your Changes file according to the spec 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 :-)

Cheers,
Sergey

PS: I'm doing this because I'm on a quest to help improve CPAN:
