setting window title on suckless terminal do not work

[ragnarov]

Bug summary

Weechat don't change terminal's window title on suckless terminal.
But vim can change the title.
Also I have scripts that can do it.
Someone from #suckless (oftc) suggested the problem was here :
https://github.com/weechat/weechat/blob/master/src/gui/curses/gui-curses-window.c#L2589

I also talked to the devs at irc. This is here as a reminder.

Steps to reproduce

Just run weechat.

Current behavior

Don't change title.

Expected behavior

Should change title.

Suggested solutions

    else if ((strncmp (envterm, "xterm", 5) == 0)
             || (strncmp (envterm, "rxvt", 4) == 0)
             || (strncmp (envterm, "alacritty", 9) == 0)
             || (strcmp (envterm, "Eterm") == 0)
             || (strcmp (envterm, "aixterm") == 0)
             || (strcmp (envterm, "iris-ansi") == 0)
             || (strcmp (envterm, "dtterm") == 0))
    {
        printf ("\33]0;%s\7", new_title);
    }

Add st to that list.
Or make that the default condition.
