Depositor missing 'timeout' attribute used with self.do_http_request

[nausicaa-rose]

Hello,
I've found your library useful, but encountered a bug recently. crossref.restful.Depositor has several methods that expect to pass the the attribute self.timeout as a parameter to self.do_http_request, which throws this error: "AttributeError: 'Depositor' object has no attribute 'timeout'" because self.timeout is never initialized.

I did a quick patch by adding timeout=100 to Depositor.__init__()'s parameter list and adding self.timeout = timeout in the body of the init, which fixed the issue, at least in my very cursory testing.

If the above is an acceptable solution, I'm happy to test it out more thoroughly and submit a pull request. If you'd prefer another approach, I'd be happy to help with that as well.

Thanks for creating and maintaining this library!
