Removed unnecessary "underscore" dependency (thanks to omega)
Fixed global leak of Client (thanks to sreuter)
This is the 3rd statsd client for node.js. I don't like to re-invent the wheel and
I must admint it's really a bad thing. However, I need a simple but working statsd
client and it seems that (at the time of writing) the other modules suffer small
bugs that prevent me to put it in production. Now you know cause there're 3 modules
for such a simple client.
