Title: Collection.add(): trigger `merge` event on model when called with {merge: true}

In my opinion it's relevant to be able to distinguish the ways changes can be made to a model's data: via server- or user interaction\*.

\*By server interaction I mean *'retrieving data changes from an (external) source'*. By user interaction I mean *'changing data by a user's direct input actions'*.
