compile-fc-batt: allow possible third field in source lines
Battery tables maintained in the fc-battery-conf repository will now
have a third field added, defining thresholds for the battery bars icon,
and there will be a new utility to compile them into the new
/etc/batterytab2 file read by the FC Tourmaline version of our
FCHG driver. For backward compatibility with the original Magnetite
version of FCHG, compile-fc-batt remains the tool for compiling the
original /etc/batterytab file format, and it needs to ignore the
newly added third field in battery table sources.
