setup.py missing. (higher priority bug for packaging)

[ghost]

Please provide an setup.py file
I am not yet working on PyBitmessage (upstream pybitmessage, not mailchuck branch, although the same issue applies) because there's other things first I need to package, but a first run for GNU/Guix (on GNU/GuixSD) and looking into other distribution shows that some people are writing some sort of temporary setup.py or use manual setup instructions.

I think this is similar or equal to Bitmessage#171

Thanks,
Ni*

I have created a setup.py draft in this commit.

Many of the require statements need to be modified to work with setup.py, but when I change them PyBitmessage fails to start when run normally. It never displays the GUI but gives no error message either.

The bitmsghash module also needs some modification. It will get compiled, but will not get loaded.
