- Implemented history report.
- Improved (not to the point of them working) filters.
- Improved automatic filter construction.
- Removed obsolete members from Task.
- Added tag support to the "add" command.
- Implemented info report.
- Removed odd Subst and Sequence objects from Task - are they just
vestigial limbs, or did I add them for a good reason? They are
gone now.
- Added Filter::applySequence to replace old filterSequence.
- Removed obsolete report.cpp filter function.
- Modified Record::get* methods to be const.
- Implemented TDB2::add.
- Renamed Task::valid to Task::validate.
- Implemented Task::setEntry to default creation time.
- Fixed bug where TDB2 was opening files "rw" instead of "r+".
- Renamed T2.h -> Task.h, T2.cpp -> Task.cpp. This permanently avoids
the problem where g++ on OpenBSD 4.5 fails because of the T class,
which probably conflicts with C++ templates. Who knows.
