Removing <a> tag in exchange for a more logical <div> tag

-Changed `<a>` tag to `<div>` in list.js
-Changed `<a>` tag to `<div>` in twelvehourclock.js
-Changed all references in flipclock.css and flipclock.scss from a to div.facesWrapper 

Removing the `<a href="#">` tags so that way if a user clicks on a number in the FlipClock they don't get pushed up to the top of the page. Changing to a `<div>` since no link is actually necessary here. Changing necessary CSS files that referenced the original `<a>` tags.

This solves Issue #152
