[envs-team]Security Info about Weechat

Dear envs user

FYI: weechat (the default irc client on envs) enabled logging per default! Please disable it! all users on the server can read your logs in `~/.weechat/logs/`!

in your client you can typ:

/set logger.file.auto_log off /set irc.server_default.msg_part "" /set irc.server_default.msg_quit "" /set irc.ctcp.clientinfo "" /set irc.ctcp.finger "" /set irc.ctcp.source "" /set irc.ctcp.time "" /set irc.ctcp.userinfo "" /set irc.ctcp.version "" /set irc.ctcp.ping "" /save

i disable weechat logging for new users in `/etc/skel/` https://git.envs.net/envs/skel/commit/11ec09cfa71367ec423771a65e4039f1236d13...

even though everyone is responsible for their own account, I'm sorry I didn't realize it until today.
