Hover interactive tracking map

hover participants & points of interest in the list, in the map, and in the elevation chart

We made orientation in our interactive tracking map more intuitive. That way spectators get a better overview of the action of the sports event. Users can now hover and select participants or points of interest in the list, in the map, and in the elevation profile. Each corresponding element is highlighted, automatically. Additionally, an arrow moves on the track while hovering over the elevation profile.
