Add an action panel to the GUI.

With action customized for MaMuT.
We cannot reuse the TrackMate action logic, for it depends on the
TrackMateGUIController, which does not fit the MaMuT context.
So we have a specific MamutActionProvider that serves actions. These
actions are however inheriting from TrackMate actions.

Make a proper MaMuT action to extract a lineage stack.
