Diagnostic build: log each connection and each notification

Browse Source 
On firmware 13.52 the service now starts and answers the launcher, but a
browser on the network gets its connection closed, and no notification
appears. The diagnostic build now logs, for every connection from another
device, what it asked for, what it was sent, and why it was closed (send or
recv errors with errno, the 10-second timeout with the first byte received),
plus the result of every notification request. The diagnostic screen shows
its build time and, while Control4Free runs, asks for the address to be
opened and page 2 screenshotted. It also reads GoldHEN's SDK version
correctly: GoldHEN returns it through the call's error value.
