- The verbosity token 'special' now controls whether the feedback is provided
when special tags are added to a task.
- Added new 'special' verbosity token documentation to man page.
- Added missing 'next' special tag to man page.
- Added new localized strings for describing special tags.
- Task is no longer a map of string to Att. Att is itself a name/
value pair, so the name was redundant. Task is now a map of string
to string. This brings the obsoletion of Att much closer.
- Removed the last uses of 'foreach'. What remains is only code that
is being obsoleted, and therefore there is no need to clean that up.
- The definition of 'foreach' in util.h must remain until last.
