Fix permanent items not being placed

[Roberto-Nessy]

Changed the 2-way distinction of "is advancement" and "is not advancement" to a 3 way distinction of "is advancement", "is junk", and "neither" so that items such as maps and compasses can be prioritised over junk items in the fast fill section.

Erred on the side of not junk for most items except rupees and ammo refills.
