Reader not iterable on Python3

[jruere]

This works on Python2 and with the build in module.

Python 3.4.3 (default, Mar 25 2015, 17:13:50) 
[GCC 4.9.2 20150304 (prerelease)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import unicodecsv
>>> import io
>>> r = unicodecsv.reader(io.BytesIO(b"hello,world"))
>>> list(r)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iter() returned non-iterator of type 'UnicodeReader'

The reason why this is happening is that __next__() is not defined for the UnicodeReader. Python 2 uses the next() method and Python 3 uses the __next__() magic method. Unfortunately, that's the least of the problems with unicodecsv's UnicodeReader iterating in Python 3. The other problems are:

• the self.reader.next() method call (should be next(self.reader) in Python 3)
• the call to unicode()
• also, you'd need to use io.StringIO(), not io.BytesIO() in Python 3

OK, I guess it's not quite ready yet. :)

I've added py3 in 0.12.0 - please try it out and open another issue if you find specific problems. :)
