When logging ingame players see a warning message that says:
"Warning: Using a password on the command line interface can be insecure."
The message is also seen four times when a player uses the "/who" command..
/tpto causes these messages too, but only when it takes you to somewhere, three messages for <placename> and four for <x y z>. /kit Fish gave me the error 7 times, after saying "Kit fish given." /spawn causes the message to show up three times.
Other commands that cause this message:
Redirect mysql stderr to a file, closes #307
→ <<cset 00809d4973bf>>
Fix broke other things, now the staff online checker fails and reports no staff online at all times, and players get "./home/minecraft/logs/mysql_errors.log: Permission denied" when trying to run commands.
Actually redirect stderr instead of stdout (really fixes #307)
→ <<cset fb3be2b6df5b>>
Updated title and description as /who also causes this message.
