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. 
Find me icon should return to the bottom right corner when search results are not showing.

Two possible solutions I can think of:

1. Dynamically adjust margin based on visibility of search results.
2. Move this view to base.xml and layout relative to `pager_results_container`.

Maybe there is an even better one?
