Differences with FriendsOfBehat/SymfonyExtension

• 100% complete backward compatibility with Behat/Symfony2Extension.

• Works as a drop-in replacement for both projects and dependencies of Behat/Symfony2Extension.

the current state of Symfony support in Behat is expected to be https://github.com/FriendsOfBehat/SymfonyExtension/ though. Being 100% compatible means you also keep some of its architectural flaws.
