82 protractor webdriver man up

Some commits to start fixing our CI. This does the following:

1. Removes the old legacy `webdriver-manager update` on `postinstall`
2. installs `request` for `protractor-setup`as per #84 
3. refactors `grunt build` so it is a singular command again.

There are still some issues i will detail below that i can't get to right now.
