Tabs variants

[JohannesMerz]

It would be handy to have inverted variants and or color props for Tabs so they can be used on different backgrounds. Atm its for example not possible to use them on backgrounds similar to the brand and text color as there is no option to style them easily.

Possible props:

Set the color prop in the Tabs component, all child Tabs would then use it.

 <Tabs variant="inverted">
      <Tab name="home">Home</Tab>
      <Tab name="api-explorer">Api Explorer</Tab>
</Tabs>
