Dai Onis ghost form should have all item slots

[Edi]

All of the oni spirits have only two misc slots. I did notice this when I was doing the unit list, but since it was across the board, I figured it was intended. Perhaps the spirit is able to only move small items (which is what most misc items are, things like rings and such). I imagine that when they get killed, all of the things they were carrying drop to the ground ala Obi-Wan Kenobi getting killed in Star Wars Episode IV.

The misc slots are probably the default for the units, since all units except the vastness have some slots.

We could ask the devs whether the spirit forms of the oni should have humanoid slots, but if so, then it needs to be all across the board.
