Remove unnecessary name attribute from Update button; added class="hide", to avoid it briefly appearing at startup.
Don't show spinner at startup. Renamed setButtonStatus() to more descriptive indicateUpdateIsRunning(). Use class (show/hide) and CSS for hiding update button instead of setting the .style.display property.
Defined classes "show" and "hide" for update button.
