Alter the way Companion Updates Happen – Use Push

The AI Client code (in the browser) now downloads the new
Companion (from the service) and “pushes” it to the Companion using a
mechanism similar to the mechanism used to send assets to the
Companion. This eliminates difficulties encountered when a proxy
exists between the Internet and the AI user’s location.

Don’t Check for a WiFi Connection when running in the Emulator

Don’t Check for a WiFi Connection when running in the Emulator, even
when started manually from the launcher in the emulator. This avoids
confusion when people are updating the Companion within the emulator.
