added doctrine/data-fixtures to require-dev
updated composer.phar as the dev build was outdated
fixed entity folders
avoiding GH API limits with --prefer-source
--non-interactive apparently falls back to clone (like --prefer-source) once we run into GH API limits
--no-interaction
--prefer-source is the way to go

--no-interaction seems to have other issues
