Title: Added interrupt digits handling.

Hi!

As we think it is not always desirable that a callee can interrupt an interruptible
Node with any digit, we have improved the interrupt digit handling.

All these changes are backwards compatible.

Now you can:
- Make a Node interruptible and not interruptible
- Clear interrupt digits
- Add interrupt digits

The order of interrupt digits is changed to correspond to the ASCII
table. This makes sorting easier.
