feat: Rename all occurences of property accent to secondary (#139)

In the MD spec, "accent" color was renamed to "secondary" to be more semantically correct.

* Rename `button` property `accent` to `secondary`
* Rename `icon-toggle` property `accent` to `secondary`
* Rename `linear-progress` property `accent` to `secondary`
* Rename `tab-bar` property `accentColor` to `secondary`
* Rename `tab-bar` property `primaryColor` to `primary`
* Update documentation and examples

BREAKING CHANGE: 
The `accent` property on Button, Icon-toggle, Linear-progress was renamed to `secondary`.
The `accentColor` and `primaryColor` properties on Tabs was renamed to `accent` and `primary`.

Closes #138
