Add tabs to People app

- Move account filter into overflow menu
- Use action bar in tab and standard mode so the SearchView
is right aligned and part of the options menu instead of the
custom view in the action bar
- Make visibility of action bar home icon a style so the icon
can be hidden on the phone
- TODO: Make physical search button work on the phone so the
search box can be removed from the action bar
- TODO: Fix SearchView focus problems
