Organize search results the same as the vault

If users have chosen vault groupings and other settings, those should maybe be reflected in item grids such as search results, item picker, etc. Users are likely used to seeing their items organized this way, and may be confused at seeing them all together in search results ordered by what is effectively a "secondary" sort.

This turns out to be trickier than I had hoped, because the vault grouping only applies to weapons. So we'd have one sort for weapons and another sort for armor. To do this right we'd have to make all these item grids quite a bit more complicated.
