Content-Length needs to be set when sending empty PUTs etc. about vimeo.js

[Dashron]

Looks good for your branch, but I think this is already covered by the changes made back during the whole 503 problem: https://github.com/vimeo/vimeo.js/blob/master/lib/vimeo.js#L114-L118.

The 411 error is the replacement for that 503 error, to finally give clear error messages to node users.

Let me know if I'm totally off base here, I'll give the official lib another check when I get into the office.

Oh yes, you're right. Sorry, I should have compared my branch to the lib first, didn't know you had made other final changes.
