Github integration: merging pull requests use the wrong user name.

[adunkman]

Just a moment ago, someone else merged NodeDC/node.dc#16, and the IRC notification lied!

(notice) adunkman has just merged NodeDC/node.dc:homepage-copy into NodeDC/node.dc:master — NodeDC/node.dc#16.

I didn’t merge them, but I did author them. Likely just using the wrong key in the message.
