Update iOS TabView to use Automatic rendering mode

Todd Anglin · web-flow · commit 91ba3fa69ad0 · 2016-07-08T21:32:15.000-05:00
Change the UIImageRenderingMode for tab icons from "AlwaysOriginal" to "Automatic." This will allow icon images to inherit the `selectedColor` specified for the tabview (eliminating the need to provide two versions of every tab icon).
