Add option to disable the extension

[abdullahmorrison]

1 person (swifthorror) hates seeing the extension. If one person is vocal about it, there may be others that feel the same but are not vocal. There is no way of permanently removing it for one person through twitch so it has to be done by the extension.

Things to note:

• It should probably come back if a crazy new feature is added.
• the button to remove the extension should connote danger (like github does when deleting a repo).
• There needs to be a confirm box to make sure

The bingo tab is now so much less noticeable that this feature is not worth it.

This feature can be done by holding a few keys and left-clicking the screen. So, now it makes sense to do it.

I'm thinking it should be alt + shift + left-click
