Request: Instance boss API

[p3lim]

It has become my recent discovery that blizzard reads posts here, so Im gonna ask for this function.

Id like an API to determine if an unit is a Instance boss or not.

At the moment Im using 'if UnitLevel(unit) == -1 then' but it only counts for ?? mobs, not every instance boss.

Would be great if this could be added.

Thanks
