Fixes for the unit tests of the lib.selection module.

The contains_*() methods now should be used. And the test_Selection_ful_spin_id() unit test has
been completely deleted as this way of checking the selection object is no longer valid.

Import fixes for the test_suite.unit_tests._lib._frame_order.test_matrix_ops module.

Missing import in the unit test module for the lib.frame_order.matrix_ops module.

Fixes for the TestCase class names for a number of lib package modules.

As the test class name was incorrect, previously the test suite was skipping these silently. This
was dangerous!

Added a printout to the unit_test_runner.py if the TestCase class cannot be found.

This normally continued the test loading silently without warning that the TestCase class name is
missing or incorrect.

More cleanups of the unit_test_runner.py script.

The unit_test_runner.py script now defaults to verbose mode.

Fixes and improvements to Gary Thompson's unit_test_runner.py script.

The printouts have been improved and the script can now handle more than 3 levels of directories for
a package.

Fixes and expansion of the test_suite.unit_tests._lib package __all__ list.

More cleanups of unused imports throughout relax.
