- All tests (I hope) now properly remove completed.data on exit, which
should prevent certain non-deterministic tinderbox results caused by
residual data.
- introduced new show command to display configuration settings
- config command is used to just set config values
- modified documentation
- modified some unit tests calling 'task config' to 'task show'
- version now only displays the version number and copyright notice
- config displays the task configuration that version used to show
- configuration variable longversion is not longer needed
- Added unit tests to cover automatic colorization by priority.
- Added unit tests to cover automatic disabling of color when !isatty.
- Added unit tests to cover display of unsupported configuration
variable in the 'version' report.
- Added support the '_forcecolor' configuration variable to allow the
possibility of unit tests that test color support, yet redirect
output to a file. This configuration variable will not be
documented.
