Small QoL Improvements

[Elizara]

Okay. This is due to the newest trick gil spammers have been trying. (I don't see it often on Excal, but they usually come out of the woodwork after a update; I have seen it more often on my alt, which is on Midgardsormr.)

Is there a way that it could be fixed so that if you blacklist someone, that said blacklisted person CAN'T invite you to a party? Just that? The spammers have been spam inviting lately and that would stop that. I'd think this would be a pretty simple fix. Would really be appreciated, the gilseller spammers proly found that way to get around the filters..and it's annoying if I'm running around on a lower level job. That's when I get hit the most, btw.
