This patch cleans up the layout of the admin web page stats graphs
as well as adds in the email stats. Added the titles to each
graph, so you know what you are looking at.
This patch reworks the stats object dict and includes more data.
Also includes aprsis last update timestamp (from last recieved message).
This is used to help determine if the aprsis server connection is still
alive and well.
This patch fixes the CTRL-C signal_handler.
This patch also adds the new Messages WEB UI page
as well as the save url, which are both behind an
http basic auth.
The flask web service now has users in the config file
aprsd:

admin: <password>
