* 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.

fixed page.clickMarkAllCompletedCheckBox() to return inner promise

fixed page.enterItem() to return the promise and flattened out the thens
