Handle wizmode reporting of multi-god overflow temples better.

Instead of just listing all of the gods on the level in a
comma-separated list, comma-separated lists are printed for each temple,
and temples are separated with semicolons (so, "Elyvilon, Zin, and the
Shining One; Trog and Okawaru; Ashenzari").
