Add support for ViewPagerIndicator

This adds supporting files for Jake Wharton's ViewPagerIndicator
custom UI components.  This is being utilized for custom tab/swipe
fragments for use throughout the app.  I am still experimenting
with these new components, so it is still possible that we decide
not to use them.  This code is licensed under Apache Lincense,
