Add Composer support

[pdaether]

Please add support for composer / packagist ( http://getcomposer.org/ , https://packagist.org/ ).
There is a unofficial package ( https://github.com/robywan/fotolia-api ) but i would be great if this package can be installed with composer, too.

I second that, all you need is to add a json file to the repo and register it with packagist
