Updated the utils/unicode.py file with 2/3 compatibility.

Browse source 
NOTES:
  1. replaced unicode, str, etc with their six counterparts
  2. isinstance(obj, basestring) -> isinstance(obj, (string_types, text_type))
  3. I'm not entirely confident about the behaviour of __str__ and __unicode__ between versions
     so that might require a bit more testing.
