Keyboard shortcuts

[pbaykalov]

Thanks for a great extension!
I suggest keyboard shortcuts for common actions. Right now a lot of Twitch functions can only be used with mouse or don't work when chat message input field is in focus.
Most importantly:

• fullscreen ("f" now, must click away from text input)
• chat panel collapse
• mute
• emote menu (which is itself great for keyboard use since it has text search and accepts arrow input) - must activate chat input when closed. Clicking X button does not activate text input, that's inconvenient
• chat reply with Ctrl+up/down
• chat focus

I implemented all of that in my own userscript and I love using Twitch with keyboard now.
