Warning messages go to stdout instead of stderr

[PaperTsar]

Warning messages go to stdout instead of stderr, which makes piping output (for example json) harder. This happens with the following warning (I expect it does with the rest too):

Warning: Pycurl is not compiled against Openssl. Wfuzz might not work correctly when fuzzing SSL sites. Check Wfuzz's documentation for more information.

I tried to reproduce this bug by completely uninstalling pycurl and the error was sent to stderr as it supposed to be. The error was written using warnings.warn() which is used in the other pycurl warnings so it should give the same result.

I think this issue should be closed.
