Adding a composer.json file for composer/packagist

Composer and Packagist Integration

Composer has been sweeping the PHP developer community for finally providing a capable package/dependency manager that's easy to implement and use.

This simple file allows Klein.php to be placed on Packagist and easily downloaded/used in projects with a simple command-line tool.

All that's necessary is to:

1. Merge this pull request. 😄
2. Register (or login with GitHub) on Packagist
3. Submit klein.php as a new package (REALLY easy)

Optionally: Setup a GitHub "hook" to automatically update the Packagist after pushing to master. 👍

This would be much appreciated by the community. I could do this myself, but I'd rather you @chriso have control over your own package/library.

Thanks for this. I'll add it now

Ok registered and set to auto-update. Thanks again

Woot! :)
Thank you! This will also give Klein a little bit more visibility.
