Dive list: filter dives at DiveTripModel level
We use a QFilterProxyModel to filter out dives that are hidden according to the current filter-criterion. Instead, filter the dives already at the DiveTripModel level. Filter out hidden dives immediately when receiving them. The only difficult case is when dives are changed, because then visibility can change. This means that we have three cases to consider: 1) Visibility unchanged -> send change signal 2) Change from hidden to unhidden -> add dives to model 3) Change from unhidden to hidden -> remove dives from model Things get complicated by the fact that the tree-version of the model might have to add/remove full trips!
