I think it would be a good idea to move the logger function into it's own module.  We could still instantiate in the the core but would access via -> ```$this->lf_core->logger->add($message)```.  You can then format the messages within the module, e.g. append a timestamp. In addition, you can remove the separate logger in livefyre_import.php - the one that logs to the database and include in the global logger.
