Title: Merge methods

Added a merge(Map) method to Record and Map, to make it easier to change multiple entries. Also makes it (implicitly) possible to attach hidden meta-data to records, via the underlying `data` map. This is useful if the records are used in mapping layers that like to attach hidden storage related state to entities.
