Leave logging off by default.

Disable logging by default. The log file will not be created, but if it
already exists we'll add to it. So

BUG=none
BRANCH=none
TEST=manual

No logging:

  rm -f /tmp/futility.log
  cgpt help
  cat /tmp/futility.log        # file should not exist

With logging:

  touch /tmp/futility.log
  cgpt help
  cat /tmp/futility.log        # file should contain stuff
