* Add a new feature for tracking a given behavior by a new concept of a "behavior local ID" which is a stable 16-bit identifier for a given behavior, that is resilient to new behaviors being added and requires no additional work on the part of the behavior authors. * Add implementations for either settings lookup table, or CRC16 hashing of behavior device names for generating behavior local IDs.
