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.

Setup:
$ alias xt="python $TESTDIR/../t.py --task-dir `pwd` --list test"
Replace a task's text (preserving the ID):
$ xt Sample.
$ xt
a - Sample.
$ xt -e a New sample.
$ xt
a - New sample.
$ xt 'this | that'
$ xt
4 - this | that
a - New sample.
$ xt -e 4 'this &| that'
$ xt
4 - this &| that
a - New sample.
Sed-style substitution:
$ xt -e a 's/New/Testing/'
$ xt
4 - this &| that
a - Testing sample.
$ xt -e 4 '/this &/this /'
$ xt
4 - this | that
a - Testing sample.
