- Thanks to Tomas Babej.

- Modified tests that use the above.

- This is a bug in Color.cpp, not in the color.rules.t script, and the symptoms
  of this bug are 256-color usage when 16-colors are expected. The Color::blend
  method auto-upgradeѕ from 16 to 256, and may be the culprit. This bug is not
  important enough to fix now.

- Thanks to Alan Young.

- Now that CLI2::categorizeArgs is complete, all that remains is to make sure
  the individual commands comply.

- The Command object failed to initialize all member on construction and
  initialized them out of order (is this still a thing in C++11?).
- The _category was the only member with no accessor, which is not right.

Context is good for filtering, terrible for commands that do not take filters.

- Removed timeout for bulk.t, context.t
- Increased timeout for delete.t

- Problem was that Linux has been upgrading 16-color output, and the test was
  based on observed output, which looks correct, but actually isn't.
  We may end up marking these tests as expeected to fail, because they are not
  important.
