MINOR Updated sfYaml parser dependency to 2.0.14, use it in ConfigManifest and i18nTextCollector

Changed class loading to new file structure, moved dependency to framework/thirdparty,
rather than relying on "second level" dependencies through Zend_Translate_RailsYAML.
To be replaced by a composer dependency (+ proper autoloading) once in place.

-Symfony YAML: A PHP library that speaks YAML
-============================================
-
-Symfony YAML is a PHP library that parses YAML strings and converts them to
-PHP arrays. It can also converts PHP arrays to YAML strings. Its official
-website is at http://components.symfony-project.org/yaml/.
-
-The documentation is to be found in the `doc/` directory.
-
-Symfony YAML is licensed under the MIT license (see LICENSE file).
-
-The Symfony YAML library is developed and maintained by the
-[symfony](http://www.symfony-project.org/) project team. It has been extracted
-from symfony to be used as a standalone library. Symfony YAML is part of the
-[symfony components project](http://components.symfony-project.org/).
