Hi TasteJS folks!

This is a PR that contains a snapshot of:
https://github.com/tbranyen/todomvc to be included as part of TodoMVC's
collection.

This utilizes a tool I've been working on called
[diffHTML](http://www.diffhtml.org) that helps write components and
applications with declarative *real* HTML and hook into Virtual DOM
changes with transition hooks.

It also utilizes Redux to handle all state, since it pairs so nicely
with diffHTML it made sense to include over a vanilla approach.

Let me know what you think, thanks for your consideration!

..by waiting for DOM states instead of checking them only once.

* No need to recheckout gh-pages since the submodule already clones the branch.
* Fix / Remove wonky cp

-B is what we want here :)

Polymer CSS (css level 4 features) is causing csso problems

Skip it for now since polymer vulcanize already gives us wins.

* Delete ancient ember version

* Rename ember-cli example to emberjs

* Update image min dep

* Use vinyl fs directly for symlink fix

Fixes #1635

This will prevent invalid deploys when we encounter errors instead of a
partial complete deploy.

ref #1635

Update to Ember 2.6

* tests: cache node_modules

Move chrome to snapshots

* tests: Bump selenium version

* tests: Bump drool to v0.4.0

* tests: Remove chromedriver download

* test: Remove direct logs call.

Compiling as downloaded (with `tsc -p js/`) yields the following error:
```
js/app.tsx(12,27): error TS2307: Cannot find module './TodoModel'.
```

Update todomvc-aurelia 0.2.0 (using Aurelia 1.0.0.beta-1)

Fix TypeError: webdriver.WebDriver.Logs is not a function (#1605)

Webdriver logs in actual version of selenium should never be instantiated directly:
https://github.com/SeleniumHQ/selenium/blob/fa5ac92b451cff497e686d8e1e67c9c3101440a3/javascript/node/selenium-webdriver/lib/webdriver.js#L1429-L1432

But drool still uses selenium 2.46.1:
https://github.com/samccone/drool/commit/3770a157d218e6ea27ef9fd2e78f58105375fca0

So the fast fix is the old version of selenium.

Fixes #1605.

Do not exclude es6 example from lint

Updating the Marionette, Chaplin Comparision Link

since 
https://github.com/tastejs/todomvc/pull/1567

We can now handle es6 :)
