update requests to 1.1.0

[Pike]

I did inspect the usage of requests in django_browserid.base, and haven't found any other users in playdoh-lib, so hopefully this should be easy.

I didn't do any real testing, though, as I don't have a site that uses browserid.

When you did pip install -U did you first delete all the old requests files? Otherwise we might have left overs in there from an older version.

I did

cd lib/python
rm -rf requests
pip install -t . requests

and then magic to git rm the removed files, and git add.
