Peter/slide directions3

- Adds UI changes to multi result, single result, route preview fragment, and routing fragments. 
- Adds the ability to slide bottom of the routing fragment to reveal directions in the view raised up. 
I see now this is kind of tested in RouteFragmentTest but not really since the clicks are simulated with setCurrentItem().

Might be better to move these methods into RouteFragment and set the click listeners in code manually (or using ButterKnife!) Also see my comments in RouteFragmentTest for thoughts about how to better test this functionality.
