Correcting asynchronous testing

removes unnecessary .then() chaining in test.js as selenium-webdriver already queues calls internally

fixed confusing inverted use of idSelector variable

promisified all tests

promisified test.launchBrowser() and global test hooks

promisified test.closeBrowser()

promisified test.createStandardItems()

🛀 streamlined testOps to always return the promise and flattened out the thens

fixed testOps.assertClearCompleteButtonText() to wait for visible clear-complete button before asserting

fixed testOps.assertClearCompleteButtonIsVisible() to lazy wait for visible clear-complete button

renamed testOps.assertFocussedElementId() to .assertFocussedElement() and streamlined code

fixed page.clickMarkAllCompletedCheckBox() to return inner promise

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

renamed page.getFocussedElementName() with .getFocussedElementIdOrClass()

fixed page.ensureAppIsVisible() to wait for 'new-todo' element instead of 'main' as some frameworks build the contents after DOM-ready

fixed page.clickClearCompleteButton() to wait for actual button to display before clicking

extracted page.waitForVisibleElement() helper function

Sjs/test workup

Regression introduced in:
https://github.com/tastejs/todomvc/commit/cdd17df6705a62f5e9116bc0a5a243319af744f8

ref #1545

Updated JSCS dependency in ./tooling to latest 2.7.0

Add test to verify correct double click focus

Fixes #1560

firebase-angular: Correct directive name -- `todoEscape`

Obviously misprinted.
Miraculously worked overwriting the other `todoBlur` directive, and
"stealing" `todo-escape` attribute.

Removed globals, readability, simplified or removed components - replace PR #1559

Using the native `ng-keydown` instead

Updated to Angular 2 beta

Removed redundant steps due to modules that have been removed (spotted this by doing a clean install!)

Updated app to Angular 2 beta
  + Removed @View decorator
  + Changed directives from snake-case to camel-case
  + Added new dependency to Rx
  + Removed olf dependency to traceur (not sure this was actually needed?)

Changes to build process
 + Moved typescript configration to tsconfig.json in order to make it a little easier to understand / visualise
