Samuel Merritt e31ecb24b6 Get rid of contextlib.nested() for py3 
contextlib.nested() is missing completely in Python 3.

Since 2.7, we can use multiple context managers in a 'with' statement,
like so:

    with thing1() as t1, thing2() as t2:
        do_stuff()

Now, if we had some code that needed to nest an arbitrary number of
context managers, there's stuff we could do with contextlib.ExitStack
and such... but we don't. We only use contextlib.nested() in tests to
set up bunches of mocks without crazy-deep indentation, and all that
stuff fits perfectly into multiple-context-manager 'with' statements.
