Deprecation

- Removed version 1.x column name mapping support.
Feature Removed

- Removed version 1.x sort column support.
Removed Feature

- Old-style color names including underscores are no longer supported.
Unit Tests

- Removed color.deprecated.t, which existed only to make sure that
  deprecated color was marked accordingly.  Now that this is removed,
  the test is moot.
Unit Tests

- Added a Python TAP-compliant module so that unit tests in Python are now
  supported.  Not that there are any, yet.
