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. 
Sorry for the long thread. Just thinking out loud here ;)

So the reason the color change is so subtle is because the you are setting the background of the pager to gray rather than the individual items. We should be setting the background to gray for each instruction that is not the current, which means each instruction will need to have the concept of an active or inactive state. You dig?
