- Now that the 'diagnostics' command can detect duplicate UUID
values, it makes sense to incorporate that into unit tests that
employ multiple recurring tasks.
- Many tests referred to 'synch_key.data', which is not the correct
name. It should be 'synch.key'. This has no effect on the number
of passing tests though.
- When handleRecurrence was cloning the parent task, it failed to set
a new ID, so all the child tasks were given the ID of the parent.
- Cleaned up bug.annual.t.
- 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.
