Adjusted Bootstrap for ZF 2.5 that goes straight to zend-loader rather than the old autoloader factory path.

Bootstrap.php

protected static function initAutoloader()
    {
        $vendorPath = static::findParentPath('vendor');

        if (file_exists($vendorPath . '/autoload.php')) {
            include $vendorPath . '/autoload.php';
        }

        include $vendorPath . '/zendframework/zend-loader/src/AutoloaderFactory.php';
        AutoloaderFactory::factory(array(
            'Zend\Loader\StandardAutoloader' => array(
                'autoregister_zf' => true,
                'namespaces' => array(
                    __NAMESPACE__ => __DIR__ . '/' . __NAMESPACE__,
                ),
            ),
        ));
    }
