0.3.0

• Changed format of access log for HTTP requests - now logging user agent and login name (if authorization via Basic Auth).
• Support for X-Forwarded-For headers via real_ip_from and real_ip_header options which will log the forwarded IP instead of the one from the load balancer / proxy.
• Access log for HTTP can now be specified as a filename to which the service will log all requests.
• Fixes issue with schedule invoker which would crash if invoked at second 0.
• Updated dependencies to latest available versions.
