Fix Foulborn Icons showing on tree nodes, and foil items not importing type

[Blitz54]

Description of the problem being solved:

Foulborn jewels introduced the same issue in PoB2 that we had with desecrated items. Just copied over. Also fixed importing foil item types. I tested 4 of them and they all seem to be in the correct order as on the wiki. But not 100% sure.
