filter: add filter preset undo commands
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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
