Enhanced the ``test`` command so that it doesn't install the package, but

instead builds any C extensions in-place, updates the ``.egg-info``
metadata, adds the source directory to ``sys.path``, and runs the tests
directly on the source.  This avoids an "unmanaged" installation of the
package to ``site-packages`` or elsewhere.  (Also, fix a breaking test of
older dependency support; this should probably be removed altogether, as
long as nobody's using it.)
