Use typeaheads instead of checkbox lists for task status / priority

Summary:
Ref T4100.

This makes it slightly harder to choose, say, all priorities above X or all priorities except Y. We could add `open()`, `closed()`, `min()`, `max()`, and `not()` functions if there's a meaningful demand for them. I suspect some of these are maybe worthwhile while others aren't as worthwhile.
