Settings ViewPager now correctly handles RTL mode

Previously, the settings and support tabs were incorrectly orderded,
and had inverted transitions on click and on swipe.
Ordering of tabs now correctly displays All Settings as the default,
right tab, and the Support tab to its left. The tab headers also now
function properly in transition, and onclick.
