Since opening window is the bane of our auto-testing existence -- browsers not

configured to allow popups, and so on -- add an option to turn off opening new
windows. Patch the tests to check for open_window before using it, and bail out
of tests early if they can't find it. By default, the auto-tests.html file will
not allow any window opening. This gives us *slightly* smaller test coverage,
with fewer false positives on test failures.
