QML-UI: make dive edit almost sort of work

So this has a lot of caveats:
- right now it only works for buddy, divemaster and suit
- you have to actually exit the field with your cursor or the change
  doesn't take - that's ridiculous, there must be a far more clever way to
  do this
- because I use the onEditingFinished handler I can't do this for the
  Notes (so here's another reason why I KNOW that this is the wrong way to
  do this)
But it shows in principle how this could be done and once someone who
actually knows what they are doing gets their hands on the code I'm
optimistic that this can be morphed into something much more useful.

It does tie together the changes made in the previous commits so that both
clicking around on the dive list gives the expected results and synching
the data back to the cloud actually works.
