Log validateConfig, PrepareWebooks and doInstall errors

Prior to this commit, errors returned from the above functions
would be printed to the console, but not logged.  This meant
that if you weren't able to access the console for whatever
reason, but _could_ access the log file, you would have no idea
what went wrong if one of those function calls failed.
