Convert unicode for python3 portability

From http://docs.python.org/3.1/whatsnew/3.0.html:

"Python 3.0 uses the concepts of text and (binary) data instead of
Unicode strings and 8-bit strings."

Use six.text_type to Type for representing (Unicode) textual data. This
is unicode() in Python 2 and str in Python 3.
