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. 
Declaring android:icon here adds it to all preferences in addition to the action bar. Moving into ActionBar.Solid.Mapzen style resolves the issue.
