From an engineers perspective, whenever specifying colors from now on we should use the form:
```
color: rgb(var(--tone-red-500));
```
Please note:
- Use rgb. This lets us do this like rgb(var(--tone-red-500) / 10%) so we can use a 10% opacity red-500 if we ever need to whilst still making use of our color tokens.
- Use --tone-colorName-000 (so the prefix tone). Previously we could use a mix of --gray-500: $gray-500 (note the left hand CSS prop and right hand SASS var) for the things we need to theme currently. As we no longer use SASS we can't do --gray-500: --gray-500, so we now do --tone-gray-500: --gray-500.
Just for clarity after that, whenever specifying a color anywhere, use rgb and --tone. There is only one reason where you might not use tone, and that is if you never want a color to be affected by a theme (for example a background shadow probably always should use --black)
There are a 2 or 3 left for the code editor, plus our custom-query values
* 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
