As discussed and decided on the asterisk-dev mailing list ...

- Fix some breakage I introduced a while ago that made the timestamps option
  not functional for CLI verbose output.
- Remove the use of the timestamps option for log output, since it was not
  functional.
- clarify text referring to the timestamps option so that it is clear that it
  only applies to CLI verbose output
