Owner name in the case list

I'm using the `#` to mean "invoke a special preset behavior" as opposed to the default which is to treat it as a case property. Doing it this way (as opposed to using a different `prefix:`) lets you have stuff like `parent/#owner_name` as well. Put differently, Owner Name is still conceptually a property of a case, but behind the scenes it's implemented differently from a case property.
