this should address the failure in #2732

i am still very concerned that I can't test this on windows - I'm not used to developing for windows, so not sure that these links will work even if the test passes on windows.

is there a good AWS AMI to use for windows testing? i can run this in my own AWS account.
mention Jinja in install docs
add jinja to optional dependencies in setup.py
Miscellaneous docs fixes
Skip doctest that can't possibly work.

utils.data: Use list comprehension for uniq_stable()

This should be faster than and explicit for loop.  Also, a set makes
more sense than a dict if we only care about values.  After these
changes, the resulting code is the same as Dave Kirby's uniqify()
suggestion on Peter Bengtsson's blog [1].
