statsd integration

Hello.  Thanks for your work on the maven-buildtime-extension.  

If you want them, I made few modifications to support sending the timing data to [statsd](https://github.com/etsy/statsd/) using the [java-statsd-client](https://github.com/youdevise/java-statsd-client).  Also made a few adjustments to support Maven 3.2.1.

Cheers!
