jmeter-maven-plugin now on github

Wow, I’ve gotten a lot of requests for the jmeter-maven-plugin, for enhancements and whatnot. I originally had the code on code.google.com, but from there I have to add contributors, blah blah blah. So I moved all the code over to github, so if anybody wants to update it, now they can do so directly, through github. The page for the jmeter plugin is still here.
