Add file logging for macOS.

Browse Source 
When Gramps is launched from macOS's LaunchServices it doesn't have
a sys.stderr attached so the default stream logger goes to /dev/null.
Use a FileHandler in tht case, writing the log to $TMPDIR/gramps-pid.log.

This will help particularly in analyzing crashes where python shuts down
as there's no crash report in that case.
