Ignore composer lock, phar and vendor.
bugfix: use local vendor
Merge branch 'feature/addLogging' of github.com:dazz/oauth2-server-php into feature/addLogging
Improvements:

 * silence new PDO so that E_WARNING doesn't pollute test runs (when ppl have no local mysql)
 * make the data provider only return storage objects when they were setup properly
Merge pull request #2 from till/feature/addLogging
