Python 3 port

[larsmans]

AFAIK, all dependencies support Python 3 now.

pip install -r requirements3.txt seems to currently fail on wsgiref 0.1.2 (dependency of corenlp_xml)

[larsmans]

Huh? wsgiref is in the Python stdlib!

[proycon]

Ah right, it is, works out of the box in the interpreter.. But for some strange reason pip still attempts to download it and then stumbles over Python 2 syntax:

Downloading/unpacking wsgiref>=0.1.2 (from corenlp-xml->-r requirements3.txt (line 4))
