* Serialize broadcast_data within AsyncInfoController::base_data Adds a `broadcast:` key to our `base_data`, regardless of whether a user is logged in or not. If a broadcast is not present, passes along a `nil` value. * Initialize active broadcast (if present) when rendering main page * Allow admins to preview a broadcast's processed_html when editing * Add some fixed position styling to active broadcast * Add system specs around broadcasts on homepage * Use sanitize in place of html_safe when previewing broadcast * Do not initialize broadcast if no broadcastData available * Render default value on broadcast in options_for_select * JS cleanup * Unset fixed positioning for static navbar config Also add some default styling for an active broadcast
