Support routes

[lemeryfertitta]

Routes are a sequencing of climbs (frames) with a certain speed (frames_pace). In order to properly display a route, there should be a playback mechanism to see all of the frames for the route. One idea would be a slideshow style that allows for clicking through the frames.

For now, routes have been removed from the data to avoid confusion.

Marking this one as low priority given that there are very few routes on the board and they seem to be significantly less popular than boulders.
