update to newest version of requests

[jrus]

The requests library has gone through big changes since the April 2012 version the balanced python client requires: http://pypi.python.org/pypi/requests#history

It had some backwards incompatible changes w/ the big refactor/rewrite 1.0 release, but that's now 2 months ago, so it might be stable enough to rely on by now. Might take a bit of reworking of our code, I don’t know how hard it would be.

Also worth investigating is version 0.14.2 of Requests from the end of October, the last version before the big refactor.

When trying to run on google app engine, the python client currently fails, because requests can't find a list of certificate authority keys, and therefore raises an exception. It’s possible to work around this by leaving the same requests version and modifying the balanced python client. But it also might fix things to just use a newer version of the library. I haven’t done much testing of it.

I'm working on a branch to allow the latest version of requests but 1.x refactoring appears to have broken the documented behavior that we rely on. We can work around easily enough but am going to pause here for air.
