Can't load projects that use extensions

[eliza411]

I created a really brief Behat project to use as an example with ScenarioEd, and although it runs fine from command line, when I try to load it with ScenarioEd, I get:

Fatal error: Behat\Behat\Extension\ExtensionManager::initializeExtension(): Failed opening required 'Behat\MinkExtension\Extension' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/scenarioed/vendor/behat/behat/src/Behat/Behat/Extension/ExtensionManager.php on line 112

I'm not sure what all you need to know ... the behat.yml looks like:
default:
paths:
features: 'features'
extensions:
Behat\MinkExtension\Extension:
goutte: ~
selenium2: ~
base_url: http://scenarioed.org/
Drupal\DrupalExtension\Extension:
blackbox: ~

And the FeatureContext.php looks like:

use Behat\Behat\Context\ClosuredContextInterface,
    Behat\Behat\Context\TranslatedContextInterface,
    Behat\Behat\Context\BehatContext,
    Behat\Behat\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode,
    Behat\Gherkin\Node\TableNode;

/**
 * Features context.
 */
class FeatureContext extends Drupal\DrupalExtension\Context\DrupalContext
{
    /**
     * Initializes context.
     * Every scenario gets it's own context object.
     *
     * @param array $parameters context parameters (set them up through behat.yml)
     */
    public function __construct(array $parameters)
    {
        // Initialize your context here
    }
}

Because we're using a copy of Behat (within our own composer-based autoload env) to parse and load features, any projects that have configured Behat to load resources we don't have in our autoload environment will fail to load.

Looks like we should remove our dependency upon Behat, and use Gherkin a bit more directly.

Short term solution for now would be to exclude any extension config parameters or feature contexts that try to autoload anything that ScenarioEd doesn't have.
