* Set PHP 7.1.3 required version
I've tried to specify ^7.0 version at first, but main package which is
symfony/framework-bundle@v4.4.8 requires PHP ^7.1.3.
* Bump Symfony FrameworkBundle to ^4.4.8
Current Symfony Framework stable version is v5.0.8, but I guess it
requires significant codebase upgrade, so I've sticked with 4.4.8 which
shouldn't cause any breaking changes. Old requirement was ^3.3|^4.1
which compatible with 4.4.8.
* Bump PHPUnit version to ^7.0
PHPUnit 8.x version required PHP ^7.2, so I'm setting 7.x version to
support PHP 7.1.
There is new way to specify Kernel class, related PR:

* Bump PHP CS Fixer version to ^2.16.3
Configuration and all renamed rules fixed.
Config file renamed to .php_cs.dist as recommended in migration guide.
Migration guide from 1.x to 2.x:

* Remove PHP_CodeSniffer package
Second linter doesn't make sense. I think Symfony user would prefer
PHP CS Fixer over PHP_CodeSniffer because first one maintained by Symfony
members.
* Remove satooshi/php-coveralls package from Composer
This package is abandoned and Coveralls recommends to install it directly
in Travis-CI task script.
* Update Travic-CI config
I've changed test versions to PHP 7.1.3 and 7.2. PHPUnit generates
coverage report in report/logs/clover.xml file. Then PHP CS Fixer runs
with --dry-run option to not override anything just to show coding style
errors.
* Add basic Coveralls config
This is basic recommended config for a PHP based project.
* Add symfony/yaml package
This package was part of satooshi/php-coveralls, now it should be
defined as dev dependency.
* Do not commit composer.lock
I think committed composer.lock can cause CI errors while tests on fresh
installs are better.
* Remove confusing Ruby comment
