AbilityBuilder#addUniqueProperty allows one to register unique properties for their scriptable ability.
The previously mentioned method populates a variable in AbilityBuilder, uniqueProperties. This variable is then used in ScriptableAbility#registerUniqueProperties to register the unique properties.
There is also a demo of the unique properties in action, in the custom_ability_with_property.js script: adding, setting and getting a unique property.
The unique property comments in the script needs to be checked by Lucas
Note
I had to edit AbilityEntry#setUniquePropertyByName to "fix" the JS value. I'm not too sure if this "fix" is appropriate to do. I'll leave it to Lucas xD
