More features in the HTTP server (#16)

* Added more features to HTTP server

* Added a title to the multi-camera view page.
* Support naming cameras through a simple mapping using a text file.
* Updated some logging messages to be more verbose (and match those in pair.ts).
* Confirmed the charging status and battery level values reported back by DevStatusAck.
* Log camera status (charging, battery, Wifi strength) when connected.

* More updates to HTTP server

* Deal with Web Audio autoplay policy by starting camera on mute and adding a button to toggle the audio stream.
* Add a favicon so the server tan can be easily spotted.

The favicon file is a 48x48 32bpp ICO file, gzipped.

* Update README.md

* Describe flags and enable camera audio by default.

* Update audio button based on state change

* Update description of discovery_ip in bin.ts

* Update session start message in http_server.ts

* Update README.md

Update flags and note about --discovery_ip.
