don't print subcolors $ and ^ tags in message log. character dumps also takes from log messages.

server/display-ui.c
display_message_aux()
/* We don't need to log *everything* */
if (strchr("[", *msg)) log = false;
if (type == MSG_MOTD) log = false;

/* We don't need to log subcolors $ and ^ tags */
