Annotation sets #162

On the topic of annotations, I see the need for a way to filter "sets" or clusters of annotations that should be shown. Conceptually - I see annotations as unordered with an internal ID, then I see one or multiple annotations sets that can list these exisitng annotations, but potentially in a new order. That would open up for designing "training procedures" like a weekly maintanaince check, or daily maintenance check, or startup sequence, or things like that, where potentially the same annotation could exist in multiple sets but with a difference sequence #number. Does that make sense?

Could potentially also be feature creep for the basic user but as long as the schema supports it, it could be optional.
