Building Zip archive for python 3

[jpfairbanks]

Desired Behavior: python setup.py zip should create an archive with the distribution.
Actual Behavior: python setup.py zip raises an exception

With python version: Python 3.5.2 :: Anaconda custom (x86_64)
Steps to reproduce:

git clone https://github.com/clips/pattern.git
cd pattern && git checkout development
python setup.py zip

Output:

pattern-2.6.zip
Traceback (most recent call last):
  File "setup.py", line 46, in <module>
    print(hashlib.sha256(open(z.filename).read()).hexdigest())
  File "/Users/jfairbanks6/anaconda/lib/python3.5/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8b in position 12: invalid start byte

Thanks! The line should be print(hashlib.sha256(open(z.filename).read().encode("utf-8")).hexdigest()), if you want you can submit a PR against development, otherwise I'll fix it at the next opportunity. There might be other problems with ZIP archive creation though, this part is currently untested on Python 3...

Are you sure the file z.filename shouldn't be read as raw bytes and then hashed? The output of zipping shouldn't be utf-8 text.
