Merge #13614: doc: Update command line help for -printtoconsole and -debuglogfile (satwo)

5e362c0 Fix command line help for -printtoconsole and -debuglogfile (Samuel B. Atwood)

Pull request description:

  This is a rebased version of #13589 with the changes to the 0.16.x release notes removed.

  > #13004 changed the default behavior for printtoconsole but this has not been reflected in the command line help.

  > This fixes the description of -printtoconsole to reflect this change, and also provides the user with missing information on how to explicitly disable logging to debug.log.

  > At present I have made the latter update to two separate places (-printtoconsole and -debuglogfile) because a user looking for information on how to disable logging is probably going to look in the "Debugging/Testing Options" section. Moving -debuglogfile from the "General" options category to the "Debugging/Testing" section could potentially remove the need for this redundancy but may be out of the scope of this PR.
