Peter/tilt

- Adds resume button when the user scrolls away
- Adds tilt on default during routing
- When the user tilts the map during routing that tilt will stay consistent through out the rest of routing. 
Its best to try to avoid adding public methods that are only for testing except as a last resort.

In this case you get get a reference to the touch listener from the shadow.
