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"
Create a task file manually (no IDs):
$ cat >> test << EOF
> Sample one.
> Sample two.
> EOF
$ xt
3 - Sample one.
7 - Sample two.
Add some manual tasks:
$ echo 'Custom one. | id: custom1' >> test
$ echo 'Custom two. | id: custom2' >> test
$ xt
3 - Sample one.
7 - Sample two.
custom1 - Custom one.
custom2 - Custom two.
Rewrite the task file:
$ cat > test << EOF
> New.
> EOF
$ xt
5 - New.
Add comments to task file:
$ echo '# this is a comment' >> test
$ xt
5 - New.
