Tell MAE how we behave and what channel we listen on.

MAEDaemon means we're always running; we don't perform a task and exit.

If we optionally listened on more channels than just hello, we'd specify

that here (as second parameter).

See module MAE and MAETask for task-specific info and more.

Calling MAETask.getName() will return "hello".

When debug mode is enabled, the dbgf variable will append /usr/mae/log/hellodbg.log.
