Python 3 support

[FinnG]

I'd quite like to use this module with python 3, but there isn't support:

gfg@marty ~/Personal/git/python-phabricator $ ipython3
Python 3.3.2+ (default, Feb 28 2014, 00:52:16) 
Type "copyright", "credits" or "license" for more information.

IPython 0.13.2 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

This is done on master now and we are planning to release 0.6.0 soon with Python 3 support.
