Python 3

Cyrax doesn't work with python 3. When installing it using pip, the following error is returned:

$ pip install -r requirements.txt

It does not, that's true. :-) It could be done, though. :)

Hmm looks like one of the forks has already made python3 changes. These commits:
memiks@b5bc798
memiks@897fb59

Wonder why they haven't submitted a PR? We could just cherry pick these.

Hmmm... I'm still a little bit uneasy about dropping Python2 support. %)

[Cong]

no, we should be able to support both 2 and 3. With Travis CI it should be easy to check.
