Adds the Overwatch chat filter
It will change your own chat, so if you type "gg ez" you will say stuff like "Gee whiz! That was fun. Good playing."
Also filters chat messages from other players, but it will only show differently to you (and not for others) https://www.reddit.com/r/Competitiveoverwatch/comments/4y8cxc/trying_to_type_ggez_now_gets/
(Only English messages are currently included)
