Filter by Alt Style in item search and item appearance API calls

I'm not planning to port full Alt Style support over to the 2020
frontend, I really am winding that down, but adding a couple lil API
parameters are *by far* the easiest way to get Alt Styles working in
the main app because of how it calls the 2020 API. So here we are, just
using new parameters for DTI 2020 that I'm gonna deploy to impress-2020
first!
