Title: add error_log handler

adds [error_log](http://www.php.net/manual/en/function.error-log.php) handler to send output to webserver SAPI handler (directly or indirectly)

this is for completeness, and some usecases can't be handed without error_log, like writing to webserver sapi, so log would be written with webserver not php permissions.
