amulet tiles

Replace the octagonal amulet placeholder for the two new tiles.
Give the "cubical amulet" a hint of being cube shaped and rename
"pentagonal amulet" to "perforated amulet" because it's easier to
draw that way.

Bump EDITLEVEL now for the extra objects and monsters because I
forgot to do so earlier.
