Optionally keep sort order stable when filtering lists

For some lists it is useful to keep the same sort order when filtering (rather
than sorting by best match like we usually do). Add an optional function to
FilteredList to make this possible, and use it whenever we show lists of things
sorted by date (branches, stashes, reflog entries), as well as menu items
because this allows us to keep the section headers in the keybindings menu,
which is useful for understanding what you are looking at when filtering.
