Sometimes people tag all-way stop signs at the junction node,
othertimes people tag all-way stop signs at the stop sign location.
What we're doing here is:
- if `stop=all` tagged at the junction, show viewfield in all directions
- if `stop=all` tagged at the sign location, show viewfield according to `direction=` tag
Previously it was up to the caller to draw whatever they want into the
footer flash. With this change, uiFlash creates an icon and a text, so
the caller doesn't need to do as much work.
Between keyboard shortcuts screen and onscreen hover text, I think we have
the icons covered well enough and don't need to add it to the help. Having
it in help means that translators need to do double work.

There are several issues here.. Here's a quick brain dump:
- the requestIdleCallbacks in map.js (scheduleRedraw) seem to be causing
crashiness in Firefox on fast zoom/unzoom, mousewheel, etc.. anything where
the view transform changes a lot and the redraws don't catch up.
(commented out, reverted back to lodash throttle)
- the requestIdleCallback worker queue in idle_worker.js seems to be causing
crashiness in Firefox and Chrome when exiting the walkthrough. Something about
deferring the tile parsing as the user leaves the intro has a problem.
It might be an infinite `while` loop, not sure.
(commented out, reverted back to for loop)
- the requestIdleCallback in call_when_idle.js is only used to defer
tile loading in context.loadTiles() - this one seems fine, and actually
has maybe the biggest benefit for improving performance.

What we were doing before was d3.selecting the attribution line and
inserting the capture date into it. This was confusing the viewer
(which updates asynchronously) so that the sitelink would never update.
To make things easier, we'll just hide the viewer's built in attribution
and construct the attribution line the way we want it.
