Twitch Bonus Clicker por Sean F

Uses MutationObserver interface to track any changes to parent div element of chat bonus button. Every time this div element or its children elements are changed/updated, a function to find and click the bonus button in the page is called. The cases in which this function is called is when the chat bonus displays on the page, which then will be clicked, and when Twitch displays the small auto bonus of 10 points since this alters the parent div element of the chat bonus button but the function does not do anything in these specific cases, only when the bonus button appears.
