Refactor the Vanilla ES6 example (#1626)

- Simplify the Template module.
 - Simplify the router.
 - Convert all of the View render commands to normal methods, and give them more meaningful names.
 - Convert all of the View bind synthetic events to binding methods, and give them more meaningful names.
 - Normalize the Store API.
 - Collapse the Model abstraction, since it consisted mainly of trampolines to methods on Store.
 - Remove unnecessary dynamic templating for the Clear completed button.
 - Put .footer inside .main since they are always hidden together.
 - Make .filter a div, and unnest the <a>s inside the <li>s to avoid unnecessary extra nodes and CSS.
 - Update the tests to work correctly with the new Vanilla ES6 markup.
 - Remove unnecessary object orientation in app.js.
 - Remove boolean traps from methods.
 - Do not modify the NodeList prototype.
 - Use cross-browser copmatible NodeList iteration in dispatchEvent of $delegate.
 - Fix the existing JSDoc comments.
 - Expand the existing JSDoc comments.
 - JSDoc more of the code.
 - Use Google Closure Compiler instead of Babel. It offers useful warnings and generates better code.
 - Author a learn.json section for the Vanilla ES6 example.
