The map widget called the dive list to select dives. This is inconsistent and complex. The dive list has to call down to the core anyway. Therefore, change the code to call the common core function. This means that we have to transform integer ids into dive-pointers. That is a bit sad, because the dives were just transformed into indices. Let's address that in a future commit.
