Make sure as much as possible is written to the logs, and not stdout.
Also copy an extra 1024 bytes when fetching the system log (and continue
capturing a while after stopped, since there may be unflushed system log
data in memory).
Split out the code to prepare the simulator from the AppRunner class,
which is now just handling the logic required for each test run.
This way it's easier to handle simulator preparation for multiple
test runs with the same simulator.
Also revamp logging to avoid printing directly to the console, but
instead use the logging classes that permit redirecting logging
to a file. This makes the html report show better logging.
