Catch panics in pad task loop functions

We can then convert them into error messages or maybe return something to that matter from stop_task(). Needs some more thinking if that causes potential problems.

added Enhancement label

changed milestone to %0.19.0

Posting an error message and pausing the task seems the correct approach. If there's no parent that can accept messages, either panic again (i.e. abort the process) or just silently pause the task.
