Extra Secure Chat

Mostly patches the exploit used by gaslight by preventing sending messages to yourself, which prevents generating fake context. The exploit can still be used with multiple accounts however. There is a config option to convert all whispers to system messages to also prevent this, but it makes all whispers non-report-able so this isn't a recommended option.

Currently beta as I cant test this myself due to not owning 2 copies of the game, feel free to contact me on discord and tell me this works though and ill switch to release!
