Use recent_messages API to populate the chat on open

[AlcaDesign]

Use the recent_messages endpoint to fill a chat when it's created.

https://tmi.twitch.tv/api/rooms/:channel_id/recent_messages?count=50

Where ":channel_id" is the channel ID. count is how many to give, max 50, min 1, otherwise is 400 Bad Request error with no body.

Don't need 50 messages, but a few would be nice. There's an extra tag "historical=1" in the IRC. You can use tmi-sent-ts=1524389285409 for the timestamp. ¯\_(ツ)_/¯

(Regurgitated from here.)
