TODOs

Remove WebDriver from ctor in: PageObjects, Navigator.
Do the necessary clean-ups in Selenium too

Deprecate:

• PageObjects#waitUntil(Supplier)
• Various versions of Selenium#failFastFindElement with webdriver in signature

Implement ErrorPage#assertExists and RenderedPage#assertExists and delete their boolean exists

Selenium always does the "ui-test-initialization" (webdriver and vnc-recorder). No more lazy.
