**Refactor Locate leaflet control**

- Locate right away
- Clicking on the locate button pans to user location and zooms in a little bit
- Watch for location changes and move the marker accordingly

**Marker style and fix animation bug**
- Make stop markers smaller, add border to vehicle markers.
- Don't animate if the page isn't visible. Previously if you came back to the page after it being hidden the animations would freak out.

**Update utils to do 550/801 opposite directions**

**Use moment js to show a pretty time**

**Make the listview a fixed with of 400px**
