+1. Add the ability of console.pl to resize and have dx spots also resize so
+ that the comment field's size will increase accordingly. Sh/dx amd sh/mydx
+ also work similarly. If you make the console width smaller or wider then
+ spots already on the screen will not resize.
+2. For client programs that parse the output (why? use set/ve7cc to get more
+ easily machine parsed output), a new command "set/columns <width>" is
+ available.

+1. Add a dx spot cache which will store 2 days worth (configurable) of spots.
+ This is then used by the vast majority of simple sh/dx queries without
+ using a sub process. A simple sh/dx is any sh/dx that does not have an
+ "expression" such as "sh/dx g1tlh". So "sh/dx", "sh/dx 200", "sh/mydx" will
+ always run in the main program via the cache. Certain client programs (no
+ names, no pack drill) will notice the difference immediately. It's also a
+ bit snappier.
+2. set/badspotter or set/badnode will work for RBN input.
+3. RBN input with invalid QRGs will be dropped with a nice friendly message
+ rather than a scary exception message about multiplication thrown by one
+ of the libraries that I use.
+4. Added CTY-3126 prefixes.
+5. Silently ignore self spotting below 1240000Khz (change
+ $Spot::minselfspot to 0 to disable or some other freq in Khz). NOTE this
+ will appear as a spot to the spotter's feed, but will not be passed on.

+1. Fix long standing bug in crontabs that commands with " rather than ' around
+ strings could cause those commands not to work.
+2. Add CTY 3117 prefixes.
+15Mar21=======================================================================
+1. Fix DXUtil::localdata so that it does actually prefer the latest version
+ of a file regardless of whether it is in /spider/data or /spider/localdata.
+2. Add CTY-3105 prefixes.

1. Fix DXCron::spawn_cmd so that more than one spawn_cmd can be active at a
time. This affects many nodes where lots of regular spawn_cmds happen at
