Fixed composer.json with required package information for packagist

I have added the necessary data to add this nice package to (packagist)[http://packagist.org].

I entered the data found in one of your other packages (kuikui/memcache-service-provider)[https://packagist.org/packages/kuikui/memcache-service-provider].

Without the package name provided packagist rejects to accept the package. (see the error)[http://img407.imageshack.us/img407/187/vtca.png]

Please accept this PR and submit the package to packagist.org - (submit form)[https://packagist.org/packages/submit]
