Intercept common IO errors exceptions.
When the task directory doesn't exist or when a file can't be read or written,
t.py fails with a full stacktrace exception. This change allows t.py to fail
more gracefully, printing the exception message, the relevant file, and then
exiting with an errorlevel code of 1.

$ alias xt="python $TESTDIR/../t.py --task-dir `pwd` --list test"
Add tasks of varying width:
$ xt Short.
