Add undo commands to add / edit / delete filter presets.
These are styled after the other undo commands: On changes,
the UI is informed by DiveListNotifier signals. Editing is
a simple std::swap of values.

Even though the functionality is seemingly trivial, this is a bit
invasive, as the code has to be split into two distinct parts:
1) Post undo command
2) React to changes to the divelist
Don't compile that code on mobile.

Create a new translation unit for event-related undo commands.
Create a base class of commands that add events and one subclass
that adds a bookmark event.
Use this command in the profile-widget.

The file command_private.cpp had functions concerning selections
only. To make these functions accessible from outside the undo
machinery, turn it into a part of the core-library. Currently,
only C++ functions are exported. We might think about also
exporting a C interface.

In the future we might want to use undo-commands for mobile as
well (even if not implementing undo).
Therefore, move the undo-command source from desktop-widgets
to their own commands top-level folder.
