Berthold Stoeger 27944a52b1 Undo: don't send signals batched by trip
Since the default view is batched by trips, signals were sent trip-wise.
This seemed like a good idea at first, but when more and more parts used
these signals, it became a burden. Therefore push the batching to the
part of the code where it is needed: the trip view.

The divesAdded and divesDeleted are not yet converted, because these
are combined with trip addition/deletion. This should also be detangled,
but not now.

Since the dive-lists were sorted in the processByTrip function, the
dive-list model now does its own sorting. This will have to be
audited.
