- 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.
- Added unit tests for Config. Why didn't I do this a year ago?
- Shut off old 1.7.0 code (gulp).
- Task now thoroughly broken, and only 1.8.0 can help.
- Context now gathers messages and footnotes.
- task now calls into the new 1.8.0 code (via Context), then calls
into the old 1.7.0 code. Two for the price of one.
- Began the big integration festival by moving all objects out of
the sandbox.
- Hooked up one error message to context.stringtable, just to make
a point.
