Generate a HTML report for SageNB tests

[qed777]

It would be useful to have a HTML report summarizing the results of Sage Notebook tests, including the output and traceback, if any, of each test.

We can begin with the notebook's functional test suites (cf. #7343), but we could add doctests, eventually. And with a backend server, we might select, run, and monitor tests remotely.

Note: The patches depend on #7343. Please apply parts A and B, in order. To test the test report generator, try

sage: from sagenb.testing.run_tests import run_and_report; run_and_report()

This should run the notebook's Selenium test suite, generate and write a self-contained report.html, and open the report in SAGE_BROWSER.

Remarks:

• Part A adds HTMLTestRunner.
• Part B makes significant changes to HTMLTestRunner.py and sets up the test runner for sagenb.
• The runner captures all output, e.g., we can display information from passing tests, too.

To do, but not necessarily in this ticket:

• Stabilize the results table's column widths, especially when toggling tracebacks.
• Support multiple results tables.
• Use the runner to display doctest results.
• Use a backend server to select, run, and monitor live tests.

Mistake: run_and_report's docstring should say open_viewer defaults to True.

Doctesting may be straightforward. Given foo.py, sage-doctest preparses its triple-quoted blocks and writes them as docstrings of example_* functions in .doctest_foo.py. This file calls on itself a subclass of doctest.DocTestRunner. Since Python's doctest module can also generate unittests, we can "replace" the end of .doctest_foo.py with, e.g.,

if __name__ ==  '__main__':
    from sagenb.testing.run_tests import run_and_report
    import doctest
    run_and_report(doctest.DocTestSuite())
    sys.exit(0)

Although the test names example_* are not informative, sage -python .doctest_foo_mod.py runs the tests and makes a report!

Version 2 (of part B):

• Solves the table width problem for Cr3, FF3.5, IE8, O10, S4 on Windows XP and Cr4, FF3.5, O10 on Linux.
• Works around a jQuery / IE8 toggle bug.
• Fixes run_and_report's docstring.

Feel free to suggest improvements to the form and function of the report!
