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'm going to change the way the arrows clicks are registered from using a handler in in the base activity to registering an onClickListener in routeFragment. Testing it the way it is currently has been a disaster so I'm going to put this in a next pull request just so that the rest of this can get merged in. If by the time you've looked at this and there is a test that just means I pushed before the next pull request.
