Create something in the readme or somewhere else to highlight contributors

In another repo of mine, I wrote a command to search through the git history and find build a list of authors, maybe something like that would work? https://github.com/benprew/pony/blob/master/Rakefile#L34

There's also the contributors page in github, could link to that in the readme? https://github.com/zpeters/stashbox/graphs/contributors
