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.

Previously, single dashes were used for associatons, which makes PlantUML layout all of them in an horizontal line. I changed that to two dashes so that PlantUML uses normal layouting. I think that is far clearer.
