quake: add a new option `onlyone`.

This option allows using a single instance of the app with multiple
screens instead of having a separate app for each screen. It works
better if there is only one instance of the quake object, i.e.

  local quake = lain.util.quake({onlyone=true})

and

  awful.key({ modkey, }, "z", function () quake:toggle() end),
