Subject: [PATCH] Highlight Callsign with f/g & b/g invalid restores
 highlighting

Using a Highlight Callsign UDP message with `Highlight last` false and
specifying  both  f/g  and  b/g  colours as  invalid  now  resets  the
highlighting on any matching callsign,  as well as removing the decode
highlighting internal record.
