Replaced Left with Start, and Right with End to fit Google's new RTL API.
Replaced setPadding with setPaddingRelative (which uses Start and End instead of Left and Right) around switches to make them look right in RTL UIs
Added RTL Support to LinearColorBar in order to make App Management's storageBar compatible with the RTL UI.
Reversed App Management's ViewPager in RTL langs
Fastscroll aligned to the left
