      Reduce the number of OSM fetch threads used for getting tiles for
      immediate display. The center tile has always been a single, dedicated,
      priority thread. There is now only one thread to fetch surrounding
      tiles sequentially. A final thread sedately sites in the background
      fetching adjacent tiles to be ready for panning motions.

      Never prefetch zoom levels 17 or higher. These are extremely detailed
      street-level views that are built on demand and place a great load on
      the servers. The only way to get these tiles is to manually pan/zoom to
      the areas where you NEED that level of detail. To see the raw zoom
      level, double-click an empty spot on the map and look at the z: on the
      top line.

      Validate overlay byte per spec. Overlays are only A-Z and 0-9. To get
      compressed 0-9, use a-j (APRSISCE/32 automatically does this for you).
      This WILL cause some stations to no longer appear, but they also don't
      appear on aprs.fi! (aprs101.pdf page 91)

      Note: If you currently use an invalid overlay, it may be reset to a
      valid value at any point. Please verify your Configure / General symbol
      setting.

      Increase validation of individual Mic-E character ranges. You can see
      the results in the "NoParse" trace log. Verified my new rejects vs
      APRS.FI's raw log interpretation of the same station.

      View / None with Screen / Paths checked now labels the path links on the
      screen and (theoretically) no longer displays ME's paths unless it is
      the center.

      Station information popup now contains HeardBy: and Hearing: entries
      with callsigns of direct (not digipeater) stations. Note that this can
      make the popup really wide for a busy station, but it's the quickest
      place I have to show the info right now.
