- Now that the 'diagnostics' command can detect duplicate UUID
values, it makes sense to incorporate that into unit tests that
employ multiple recurring tasks.
- Rewrote updateRecurrenceMask, which was hopelessly muddled after the
TDB -> TDB2 change.
- Modified associated code.
- Improved signal to noise ratio in unit tests.
- Corrected all unit tests that used the old syntax "task done 1" to
use the new syntax "task 1 done". Similarly, "task 1 ..." is now
"task 1 modify ...".
- Fixed bug that caused multiple recurring child tasks to be generated
under certain circumstances.
- Removed text.t.cpp tests that are not in task.
- Added Bryce Harrington to AUTHORS file.
- Corrected tests that were broken by the fix.
