Update service config for config file caching; Update of classmap

The current configuration has closures in the service manager configuration (in config/module.config.php)

This gives problems when the config is cached by ZF2 (http://akrabat.com/zend-framework-2/caching-your-zf2-merged-configuration/#comment-133929)

By moving the factories to a separete config-file, this issue is resolved.

The classmap has also been updated
