Query param simplifications: Move more params into main query classes

[nimmolo]

Gets us a huge step closer to handling index params in a predictable way, and vastly reduces the number of Query subclasses. Should not change anything on the front end, however!

Front end tests: We want to be sure that the links for these still work as expected. I believe all the important ones are well tested though, so if this seems like a ridiculous number of indexes to check, please just spot check.

Or not. I'm inclined to just merge it and move on, i'm sure we'll hear about it if anything's not working as expected.

Appreciate all that testing, @JoeCohen
