Undo: implement rudimentary support for undo of dive-splitting

Browse source 
For this, the core functionality of the split_dive() and
split_dive_at_time() functions were split out into new
split_dive_dont_insert() and split_dive_at_time_dont_insert(),
which do not add the new dives to the log. Thus, the undo-command
can take ownership of these dives, without having to remove them
first.

The split-dive functionality is temporarily made desktop-only
until mobile also supports "UndoObjects".
