Berthold Stoeger 75ef8b68a1 map: call set_selection() core function to select dives
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.
