Support PHP CS Fixer

[keradus]

Hi.
Are there any chances that you would add PHP CS Fixer to collection of supported tools ?

How would you like to use php-cs-fixer in phpqa?

It can be added to suggested tools. But I have a doubt about usefulness. phpqa analyzes code. If you run analysis twice, you'll get the same result. php-cs-fixer isn't like that. It can fix code in CI build, but changes aren't committed. Wouldn't be better to install phpqa and php-cs-fixer separately?

in same way that phpcpd or phpmd or anything that is currently supported.
PHP CS Fixer could fix indeed, but it could also generate violations report.

@zdenekdrahos You are right that changing code style errors in the ci build does not make any sense. However, if php-cs-fixer is run with junit as output (optionally in "dry-run" mode, to not change anything and produce the same results every time), it is a static analyser just like phpcs.

Ok. php-cs-fixer gonna be in the next release.
I'll ask you for your review in a PR.
