This adds sets of CSS button variables that can be overridden in themes.
This won't change any default styles, but just provides a less
problematic method of customization.
The current suggested way of doing this is with SCSS like so:
```scss
.btn-default {
@include btn(
$text-color: var(--tertiary),
$bg-color: var(--secondary),
$icon-color: var(--tertiary-high),
$hover-text-color: var(--tertiary),
$hover-bg-color: var(--tertiary-very-low),
$hover-icon-color: var(--tertiary)
);
}
```
The trouble with this is that it brings along _all_ the btn mixin
styles, so you also end up re-setting things like this, in addition to
changing colors:
```scss
.btn-default {
display: inline-flex;
align-items: center;
justify-content: center;
margin: 0;
// and also the colors
}
```
That can problematic because it can override existing button styles
(e.g., if you already altered a single instance of margin). With these
new CSS custom properties, you can avoid this by doing:
```css
:root {
--d-button-default-text-color: var(--tertiary);
--d-button-default-text-color--hover: var(--tertiary);
--d-button-default-bg-color: var(--secondary);
--d-button-default-bg-color--hover: var(--tertiary-very-low);
--d-button-default-icon-color: var(--tertiary-high);
--d-button-default-icon-color--hover: var(--tertiary);
}
```
So now you can override the button colors without bringing along other
styles from the btn mixin.
I also removed an old `.btn.hidden` style, as we already apply
`!important` to the `.hidden` class elsewhere. Comments have also been
updated to pass our new linting rules.
