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. 
Another option would be to use a CompoundDrawable here... this entire LinearLayout could be collapsed into a single TextView with a drawableRight specified via xml.

Anyway probably not be worth changing it now since this is going to be replaced with a borderless button and the caret is going away, but just wanted to point that out for future reference.
