* CSS for moving from a horizontal main menu to a side/vertical one

1. HashicorpConsul now uses <App />
2. <App /> is now translated and adds 'skip to main content' functionality
3. Adds ember-in-viewport addon in order to visibly hide main navigation
items in order to take them out of focus/tabbing
