[Feature] Sounds for PartyChat Messages

[ZepsiZola]

Proposed Feature Description:

I would like it so that I can make a sound play every time someone sends a message in partychat. Perhaps players can individually choose whether they want the sound to play or not.

Proposed Feature Functionality:

Just have a config option that lets me pick what sound will play when a player receives a groupchat message. This is already a thing for @ and /msg, so why shouldn't the plugin also notify the player when they are messaged in partychat since partychat is basically a form of private-messaging in a way.

It would also be cool if players were able to toggle whether they want sounds to play when they are @'ed, /msg'ed and /pc'ed, but I would like it if the sounds were already toggled on by default.
