Added a change log file

Hi,

I've found your new module through Brian Cassidy's [CPAN::Changes Kwalitee Service](http://changes.cpanhq.org/). This is a service for validating CPAN change logs. Since your module didn't have one - I've added it.

Following consistent format means that various tools can more easily process your distribution automatically.

Cheers,
Sergey

PS: I'm doing this because I'm on a quest to help improve CPAN:
