Switch new files to unix line endings I thought we had this automated, but Lubomirs commits introduced a few files with dos line endings. This is purely a change of line endings, no other changes.

Map: remove LocationInformationWidget::coordinatesChanged signal This was used by LocationInformationWidget to instruct the map that the coordinates of the current dive site has changed. There is no reason why this couldn't be a function call, as no other object ever connect()s to this signal. In fact, such a function already exists viz. updateLocationOnMap. Therefore, replace the signal by a simple function call. Moreover, the uuid and coordinates of the dive site were transported via the global "displayed_dive_site" object. Instead, pass this information in the parameters of the function. This makes it easier to reason about data- and control-flow.

Map: reload on selection change directly When changing the dive selection, we have to reload the map to show the correctly highlighted flags. Do this directly by hooking into the DiveListNotifier::divesChanged signal instead of indirectly via the MainTab. Moreover, on reload center on the highlighted dive sites.

Map: don't fully reset model on selection change When changing the selection the MapLocationModel was reset. This lead to crashes on Qt-5.9 which are due to QML accessing data that was freed during model reset. This putative Qt bug doesn't happen on newer Qt versions. At least Qt-5.12 is known to work. Instead of fighting the bug, let's simply not reset the model but send a dataChanged() for every element of the MapLocationModel.

Desktop: show all selected dive sites on click When clicking a dive site on the map, the QML code would set the selected dive site, but then all dives of dive sites in the vicinity were set. But still only the clicked-on dive site was shown. Therefore, don't set the list of selected dive sites in QML, but later in DiveListView::selectDives(), where we know all the dives that were selected. This, again, gives nasty entanglement of diverse widgets and models.

Map: generate pixmap name in model Experimentation has shown that the image of a flag will only be changed after dataChanged() if it is a simple property. The old code had a complex QML expression and then - for some reason - it didn't work. To give us better control over the flags and avoid full reloads of the map therefore introduce a model-property pixmap name. The name depends on whether the site is selected and if not, whether we are in divesite-edit mode. This makes the code rather convoluted. Firstly, we have to save whether the site is selected in the map-item. Secondly we have to access the global map-widget, which in turn has to go to the map-widget helper (layering violation!).

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.
