add support for a statsd styled message

[delphid]

Hi, benhoyt, just be utilizing this awesome package for sending metrics to a statsite server. And did some customization in order to comply with the statsite/ statsd protocol.

• the default graphite protocol: {metric} {value} {timestamp}
• the statsd styled protocol: {metric}:{value}|{type}

Just in case if anyone else would need this feature, would you like to check out this modification:
the forked branch

Nice, thank you for the link! I don't think I'll include this in graphyte itself, but maybe I can link to your branch in the README.

[delphid]

Yes, nice consideration. Thank you.

I've added a link to your work to the bottom of the README now. Thanks!
