Add full support for Config/TreeBuilder

[ruudk]

Fixes #130

It took a bit more work than I expected.

I have tested this on my project and it works fine now.

@bendavies Could you please validate if it works?

Apply this to your composer.json:

    "repositories": [
        {
            "type": "vcs",
            "url": "http://github.com/ruudk/phpstan-symfony"
        }
    ],
    "require-dev": {
        "phpstan/phpstan-symfony": "dev-full-tree-builder"
    }

and then run composer update phpstan/phpstan-symfony

I think it can be done even simpler.... let me give it a shot.

Tested it on my project again, all good.

@bendavies If you can, please give it another run
