* Update box-shadowing for cards and radio buttons to low
* Update box-shadowing for hover cards to middle
* Create a new box-shadow CSS variable for form elements
This includes an update of our CSS npm module. The majority of this is
just moving files from one folder to another.
1. %breadrumbs: As well as moving we've added 'milestone' breadcrumbs
2. %checkbox-group: Moved
3. %radio-group: Moved
4. %sliding-toggle: Moved (used to be called just %toggle)
5. %form-elements: Moved and added a new %inline-alert for form field
messaging (see Structure design system)
6. %action-group is now a composition of %menu-panel, %toggle-button,
plus edits to existing style to bring the %action-groups inline with the
dropdowns from Structure). %action-group also includes a composed
%confirmation-alert that is yet to be include. This will be compiled out
until we integrate it.
We've also removed some of our old icon placeholders as the above
work seased to use some of them.
Now we done this I'd say all in all over half of our CSS components now
use the CSS npm module.
The CSS specific to Consul UI also uses much of this CSS module by way
of helper placeholders such as our %frames.
