Title: Mixmuffins logstash 1106 file output log rotation date fix

Added date-based log rotation functionality via a configuration variable called suffix_string; When instantiated with a date/time following the ISO8601 format (e.g.%Y-%m-%d), date/time-based log rotation will be utilized and events will be placed files of the specified name based on their logstash-generated timestamps.
