Summary: Add "impossible task" handling

Initial Comment:
We need to have a way of telling the user of a Task
that the action to perform is not possible. (like the
destination is unreachable in Tasks.Walk).
I guess the cleanest way of doing this is to throw an
exception that will be caught by user object.
