added a way to enable/disable PHP support when parsing a YAML input via Yaml::parse()

Browse Source 
PHP support when parsing a file has been disabled by default.
If you do need PHP support when parsing a YAML file, enable it via:

    Yaml::setPhpParsing(true);

As of Symfony 2.1, PHP support is disabled by default, and support will
be removed in Symfony 2.3.
