I have disabled the "MOTDEnabled" function in MTAServer so this exploit will become a non-issue in any circumstance when I release 0.5r2. Since the ingame MOTD feature doesn't work anyway, there's no point in being able to use it. Rich MOTD still works, of course.
I also fixed up a bunch of text strings to correct some minor typos, which is just about all I can do to MTAServer without having its source.
