Add a page level spinner

You can add a page level spinner along with a curtain on page change that can stop unnecessary clicks while page load is under process.

This will also provide a definitive indicator for the user that a new page is loading. The curtain also keeps the user from clicking other links while the page is loading.

To include this behavior, set the enableSpinnerOnPageLoad flag to true in cc-store-configuration-1.0.js.
