As we now have a separate Author entity, which holds information
about an author (the color), the Authorship name became confusing.
Edit seems to be a better name, as the entity saves information
about a change in a note.

The precision of sqlites datetime() timestamp is only one second (see https://www.sqlite.org/lang_datefunc.html). Therefore we could not order revisions of one note that were created in the same second. To remedy this, the primary key was changed to a monotonically increasing number, which solves the ordering problem.
