Properly update macros

[TheComamba]

One problem is that actors can have the same name. But maybe that's an edge case that we simply don't service.
Alternatively we work with the actor id. That's probably much easier.

Acceptance criteria:
Create a macro whenever new actor becomes (!) unkenny.
Delete the macro when that actor becomes un-unkenny.
Delete the macro when that actor is deleted.
Re-create macro if the actor name changes.

Solution 1:
Hook actions into the events above.

Solution 2:
Write an updateUnKennyMacros function that loops over all actors and macros and synchronises them.

Solution 3:
Do both, calling updateUnKennyMacros on init hook.
