App 2.31.1: log the cruise control while driving, with every assist value

The 2.27.3 log wrote a line only when the target speed changed, so the
car showed one line at the start. Now a line is written on any change of
a mode or the target and every 2 s while driving, with the raw
driver-assistance properties (target speed, assist and speed-assist
modes, the followed object) and the reason for any unread value. The
last 600 lines are kept in an appended file; the Logs tab shows 150.
