Lifetime management of Triggers is unlike anything(?) we've dealt with in Ardour so far. The parent object (Triggerbox) has a normal lifetime pattern, but Triggers can come and go in a way that few other objects do (although Processors and particularly PluginInsert are somewhat similar). We do not want the GUI to hold references to the actual Triggers, because the end of life of a Trigger is not really a signal for the GUI element to go away (the Trigger will be replaced in the slot). Consequently, we do not want TriggerPtr used as a member variable anywhere in the UI. Instead we use a TriggerReference which can "lookup" a Trigger on-demand (by box and slot number). The (G)UI now uses these exclusively. Work still needed to pick up trigger swap signals from the boxen.
