remove protobuffer dependency from setup.py about riak-python-client

[bretthoerner]

@digit604 protobuf is a valid Python package that's required to use the Protocol Buffers interface to Riak, it's available here: http://code.google.com/p/protobuf/downloads/list

Though maybe this should be optional and an error could be raised if you try to use the protobuf client without the package installed.

The problem here is that in a recent version of protobuf (currently 2.4.1) setup.py has moved into from /setup.py to /python/setup.py and this is killing the PyPI packaging. The current solution is to manually install protobuf from src, then "cd /python && python setup.py install" to get the python package.

We (Disqus) got the protobuf package working finally, patches have been submitted: https://groups.google.com/forum/#!topic/protobuf/SufLZXt-UqM

We use our own PyPI mirror, though, so we're already deploying this in production. If the patch isn't accepted quickly it might make sense to have a forked PyPI module protobufs-that-work or something and require it in the Riak client, instead.

+1 -- it is a real pain to install protobuf separately.

FYI, protobuf pip install problem is discussed here:

I really want this solved.

Closing this, assuming #113 gets merged promptly.
