Cleanup. Moved BaseExtensionInterface and corrected path in BaseExtension and Extensions classes.
Moved CacheServiceProvider to Provider folder. Just like Silex structures it.
Moved ConfigServiceProvider to Provider folder. Just like Silex structures it.
Moved ExtensionServiceProvider to Provider folder. Just like Silex structures it.
Moved the other providers as well. Also removed unnecessary arguments (empty array) for some of them.
