    *			The hostname of the site we're setting the config for. Must be the same as what's defined
    *			as @match in the metadata block above.
    *
    *		ads: Boolean
    * 			This tells us if the site we visit has ads (this refers to banners of any size, mostly from Google). We'll then trigger the removal function for that.
    *
    *		autologin: String
    * 			This is a selector for a link which has to be visited in order to get forwarded to the login page.
    *
    *       trigger: Array of Functions
    *           Triggers may or may not be site specific; they are usually for task solving and can be reused on unmodified instances of poorly programmed website scripts.
    *
    *		clickables: Array of String
    * 			These are CSS Selectors which will be buttons to be clicked (in ascending order). Some may not be clickable but each click that doesn't need to be done is already a success.
