Explore: several values per filter, !value to leave one out, *.domain

Each explore filter takes several values, comma separated (any of them), !value to leave one out, and *.example.com for a name and the names below it. Every value is a chip with its own ✕; clicking a value in the lists adds it, and hide leaves it out. The filter bar's fields take lists. domain= still works.
