Title: skip blank lines in multi line input

Some statsd emitters put a double \n\n in the output of multi line statsd stats. This causes the entire message to be treated as failed, when there is an easy fix here. Same behavior as statsd itself https://github.com/etsy/statsd/blob/master/stats.js line 205 or so.
