New XFLAG: MAX_MSGLEN

<Fredfred> what about an option TALK_SIGNS, users can only talk with a special amount of characters?
<Fredfred> so, we set it to 30, and users only can use 30 chars per sentence
<Fredfred> :D
<Fredfred> or 20, or 50
<Fredfred> that would stop those spammers, right
<Kobi_S> oh, I see what you mean now
<Kobi_S> interesting idea
<Fredfred> yeah, most users have short messages
<Fredfred> "H‎"
<Fredfred> how are you?
<Fredfred> blabla
<Fredfred> but not 30 or 40 chars
<Fredfred> I think the spam message before has more then 100 chars
