Undo: implement undo of dive site editing
This one is a bit more tricky. There are two modes: set dive site
and set newly created dive site. This is realized using an OO model
with derived classed. Quite convoluted - but it seems to work.
Moreover, editing a dive site is not simply setting a value,
but the list of dives in a dive site has to be kept up to date.
Finally, we have to inform the dive site list of the changed
number of dives. Therefore add a new signal diveSiteDivesChanged.
To send only one signal per dive site, hook into the undo() and
redo() functions and call the functions of the base class there.
