This change allows the user to change the mode of their previous trip. The original sensed mode is not changed, an object mode_confirm is added to the section of the trip. mode_confirm includes the ts, tripId, sectionId, mode value and mode text. The user can change the mode by tapping on the section lineString of the leaflet map. We already have a listener to receive incident of a trip if the user presses on the trip or section lineString. So to make things simple, a button is included in the detail screen to take user to edit mode screen. After the user pick all the modes they can either save or cancel their edit. While editing the lineString does not change color to show the mode, however, there is a temporary marker on the line to show where the user split the trip. After they save the color changes to show the respective modes. Also, the list screen only shows choose mode button for single mode trips.

the mode_confirm object has {end_ts, label, start_ts, trip_mode} keys

Done: Add more colors to represent each mode in the set
Done: Change Detail and List sensed mode icons to mode_confirm mode icon
