javascript-unittest example: README updated to the AAL model
Examples: GT javascript-unittest dropped
fmbtandroid: Ini made part of the public interface

Ini used to be known as _DeviceConf in the internal
interface. Backward compatibility with code that uses
fmbtandroid._DeviceConf is maintained.
test_engine: execute actions in model in interactive mode by default

"option execute model" is turned on by default. This is more sensible
default than execution in adapter only in the era of AAL.
fmbtandroid: the first version of visual logging added

device.enableVisualLog("mylog.html") starts logging method calls to
given HTML file. Log includes screenshots with clicked coordinates,
found icons and detected OCR words highlighted.
