Collect other apps' menu bar items into a hamburger panel

The menu bar icon is now a hamburger whose panel gathers every other
app's status item via the Accessibility API, so tray icons no longer
need to be hunted down across the menu bar. Items can be opened from
the panel, and a best-effort toggle pushes them off the real menu bar
so they only live there.
