Add changelog

[nomeata]

Hi,

binary (like many other Haskell libraries, unfortunately) does not have a proper changelog file that collects, per release, the user-relevant changes. With hackage now showing links to changelogs, it is a good time so introduce one. It would also prevent me from bothering you with #44...

Thanks,
Joachm

That's an excellent idea.

I did write a blog post http://lennartkolmodin.blogspot.ru/2013/03/binary-07.html about recent changes, but of course, it's not what a user of the library would go and look for. It should be moved to a changelog.

Accepted Hackage changelog file names are documented here: https://github.com/haskell/hackage-server/blob/master/Distribution/Server/Packages/ChangeLog.hs

You call that documentation?
