The app is unimaginatively called "Mobile" for now.
Runs but crashes pretty quickly after loading the document by the LO
core. Will need some heavy changes to get a ClientSession object
created in there, too, to handle the (emulated) WebSocket messages
from the JavaScript. It would then handle some of these messages
itself, and forwards some to the ChildSession, which in this case is
in the same process. Now the messsages from the JavaScript go to a
ChildSession, which is wrong. As the assertion says, "Tile traffic
should go through the DocumentBroker-LoKit WS"
