Organize unit tests for ``docutils/utils/*`` in a separate directory.
Create new directory ``test/test_utils/`` and move the test scripts
for modules under ``docutils/utils/`` there.
Also move the provisional "extra" test script for external TeX to
MathML converters. Add SkipTest statements so that it only runs
standalone. (The test script takes > 27 seconds, i.e. 5x more time
than the remainder of the test suite).
Name all ``__init__.py`` test scripts ``test__init__.py``.
