Dirk Hohndel 16c082112c QML UI: pick new highest dive number when manually adding dive
It's possible that this will create an out of order dive list, but it
seems the most consistent way to do things and to avoid more than one dive
with the same dive number (which could have happened if you add several
dives manually that are not the newest dives in the dive list).
