Remove all ui test dependencies from package.json

Given chromedriver was already an extra dependency that needed to
be manually installed, I have now moved all of the webdriver.io
dependencies out as well.

A new script has been added to install all of the ui test dependencies.

The Grunt file has been updated on how it checks for the missing
deps.
