- Relocated longUsage and shortUsage to report.cpp, where they belong,
which has the positive side effect of allowing all the compiled unit
tests to link.
- Renamed files task.h -> main.h, task.cpp -> main.cpp. This is to
prepare for the next rename, which addresses the OpenBSD bug.
- Removed utf8.h, utf8.cpp from Makefile.am, which were inadvertantly
added.
