Merge 1334eded62 into d0018a8cd3

this patch adds table formatted output for the stats in the
aprsd dump-stats command.  You can also show the stats in raw json/dict
format by passing --raw.  You can also limit the sections of the
stats by passing --show-section aprsdstats

 Web Admin Interface
 ===================
+APRSD has a web admin interface that allows you to view the status of the running APRSD server instance.
+The web admin interface shows graphs of packet counts, packet types, number of threads running, the latest
+packets sent and received, and the status of each of the plugins that are loaded.  You can also view the logfile
+and view the raw APRSD configuration file.
+
 To start the web admin interface, You have to install gunicorn in your virtualenv that already has aprsd installed.

+Building your own APRSD plugins
+-------------------------------
+
+APRSD plugins are the mechanism by which APRSD can respond to APRS Messages.  The plugins are loaded at server startup
+and can also be loaded at listen startup.  When a packet is received by APRSD, it is passed to each of the plugins
+in the order they were registered in the config file.  The plugins can then decide what to do with the packet.
+When a plugin is called, it is passed a APRSD Packet object.  The plugin can then do something with the packet and
+return a reply message if desired.  If a plugin does not want to reply to the packet, it can just return None.
+When a plugin does return a reply message, APRSD will send the reply message to the appropriate destination.
+
+For example, when a 'ping' message is received, the PingPlugin will return a reply message of 'pong'.  When APRSD
+receives the 'pong' message, it will be sent back to the original caller of the ping message.
+
+APRSD plugins are simply python packages that can be installed from pypi.org.  They are installed into the
+aprsd virtualenv and can be imported by APRSD at runtime.  The plugins are registered in the config file and loaded
+at startup of the aprsd server command or the aprsd listen command.
+
+Overview
+--------
+You can build your own plugins by following the instructions in the `Building your own APRSD plugins`_ section.
