Triangle fixes

The first commit adjusts the order of printing of recipes with multiple ingredients of the same level to always print the 3rd persona first, so that e.g. Thanatos+Yurlungur+Cu Chulainn=Trumpeter is printed with Thanatos first.

The second commit fixes your issue #2, which I also noticed in Skadi fusions.

The third commit avoids duplicates of the same triangle recipe (4x for same-arcana fusions).
