Add composer.json (for packagist.org)

[abumalick]

We want to add this plugin as a packagist package so we can install it via composer. using : composer require kasparsd/minit

Please note that packagist.org needs to be configured too to add the package (I think you know how to do this because you have a package on there). Another thing: it seems packagist only add the packages with a release so you will need to make a new release with the composer.json in your repository.
