Titanium Tiiny Bot 0.1.16

A Tiiny that is reachable and simply has no chat model loaded is no longer reported as unreachable. When a device request fails, Titan asks the device what it has loaded and says what is true: no chat model loaded, with what to do about it, or the old sentence when the device really did not answer. The same for the voice routes, and Settings > Model carries the same state. Verified against a real Tiiny on TiinyOS 0.1.34.
