Un-selected tabs - 508 contrast issue

[gavinr]

Unselected tabs do not have a sufficient contrast ratio

To Replicate

1. Include CDN version of Calcite on a page
2. Include the tabs sample HTML from http://esri.github.io/calcite-web/documentation/patterns/#tabs (Example: https://jsbin.com/zegesov/edit?html,js,output)
3. Run the Google Chrome Developer Tools Audit (on https://output.jsbin.com/zegesov)
4. See the failing elements under Accessibility > Contrast

Just to clarify here: to fix the 508 issue, I must use the updated release (v0.50.0) AND use the translucent version of the tabs?

@gavinr yes. In the future the translucent style will be the default but right now we're just going to advise people who have compliance requirements to manually set it.

sounds great, thanks!
