* Add Routlet service and Route Component
* Add ember-assign-helper (already an indirect dependency)
* Use EventListeners for is-href instead of observing
* Don't include :active in '-intent' styles
* Remove footer and add the Consul version to the Help menu
* Tweak menu text and button styling
* Tweak some coloring and spacing
* Add slightly larger Consul logo
* CSS for moving from a horizontal main menu to a side/vertical one
* Add <App /> Component and rearrange <HashcorpConsul /> to use it
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
4. Slight amends to the dom service while I was there
