Armadillo's scute drop timer is not saved to data

The time that is left until an armadillo drops its scute is not saved to the armadillo's data. This has two effects:

1. The scute drop timer cannot be modified via commands
2. Reloading the world resets the scute drop timer

A chicken's egg timer is saved to its data, so I would expect the armadillo's scute drop timer to be as well.
