Twitch Scam Train

This extension changes the Hype Train text on https://www.twitch.tv/ to Scam Train, which is what it should have been called all along :)

It modifies the box that shows at the top of the chat, and replaces:
• The "Hype Train" text in the top left of the box
• The "Hype Train incoming" that shows at the start of the hype train
• The "hyypppeeee" text that shows when the hype train levels up
• The "Hype Train success!" that shows at the end of a successful hype train
• The "The Hype Train is long gone" that shows at the end of a failed hype train
