Remove enumerating when loading event templates

Browse source 
Just allocate the parent array and pass it to HashSet; having an ICollection, prevents resizing repeatedly and gc'ing the temp array is cheap.

Actually, only create a hashset if we're adding a gift from external DB. Saves on that allocation, and keeps the final result as an array (fastest iterating).
