Statsd multi frame ends with newline causing bad lines in Etsy's statsd server log

[rtoma]

Please remove the newline at the end of a multi frame before sending it to a Statsd server.
That last newline is causing the Etsy statsd server to output bad lines in the logging.

So use "\n" to join commands into a single frame, but not end all commands with it.

I already got this fixed in cactus/go-statsd-client#17
