Never mind. I had a couple of hours today and since this wasn't enough
for any of the big things on my todo list I instead added this feature.

Which of course leads to the obvious questions:

a) do we need to be able to remove an event as well?
b) are there other things we might want to be able to manually edit
about the dive given that we have this neat context menu now...
