[TangerineSDR] Webserver for local host

[Engelke, Bill]

Rob - regarding the packaging, we will definitely coordinate with you on that. It's gonna be quite a while before we're at that point, tho.

BTW, I will be sending you a first draft of the protocol for communication between MainCtl  (on Local Host)  and Central Control in the next day or so, for review and comment.

Waitress should be good by itself.  Maybe I'm too predictable, but I really like its dependency graph :)

Besides the small session database used by the webapp ([0]), mosquitto might try to save retained events to its own database (if we use MQTT).
I think that'll all be sqlite, though, so we should be able to avoid something heavyweight like PostgreSQL.

Nicely done!  Once you're comfortable with the basic code layout and architecture, let me know and I can start packaging it.
