Untrusted certificates and Selenium 2 in Python

gistfile1.py

"""
Dev sites often don't have proper certificates - right now, I'm working with
expired certs with incorrect hostnames.  Workarounds for using Selenium with
certs can be hard to find, especially for the Python webdriver (Selenium 2)
bindings, which have gone though many changes recently.

One way around this is to create a browser profile, but this has its own
hassles, especially if you want your test suite to work on a build box and the
box of any dev who wants to check it out and run it.

An easier way is to update the browser profile.  This is how it's done for
Python's Selenium 2.5.0 bindings and Firefox.  Other browsers will do this
differently.

The Python bindings don't enable everything explicitly, but we're just
writing to a Javascript file here, so we can control this without it being
supported.
