Btw, I'll have to fix up some of the special cases for selecting
expanded dive trips etc. So it's not complete, but the approach is
simpler and more straightforward, and I think this one is fixable,
which I don't think the old code was.

Anyway, I'd love to hear whether you can now delete dives with
impunity, but I do realize that the selection code isn't perfect.
Selecting an expanded dive trip currently selects just the trip - not
the dives under it. And while selecting a collapsed trip does the
right thing, when you then *expand* that collapsed trip, that seems to
trigger a selection change event and then gtk messes up the selection,
and we believe the new gtk selection. Or something like that.
