This patch removes the need for the RPC Server from aprsd.
APRSD Now saves it's stats to a pickled file on disk in the
aprsd.conf configured save_location. The web admin UI
will depickle that file to fetch the stats. The aprsd server
will periodically pickle and save the stats to disk.
The Logmonitor will not do a url post to the web admin ui
to send it the latest log entries.
Updated the healthcheck app to use the pickled stats file
and the fetch-stats command to make a url request to the running
admin ui to fetch the stats of the remote aprsd server.
This does some cleanup with the stats collector and
usage of the stats. The patch adds a new optional
param to the collector's collect() method to tell
the object to provide serializable stats. This is
used for the webchat app that sends stats to the
browser.
