The function DiveListView::fixMessyQtModelBehaviour() was used to expand the first columns of dive-trips in the dive-list view. This function was called everytime that the dive-list was modified. It is kind of ludicrous that external callers would have to tell the DiveListView, when it has to update its column headers. Instead, place this functionality in the overriden reset() and rowsInserted() functions, as these are the only ways that rows can be added. Change the DiveTripModel to use the proper beginResetModel()/endResetModel() pair instead of the previous full deletion and full repopulation using the beginRemoveRows()/ endRemoveRows() and beginInsertRows()/endInsertRows().
