Full run graphs

[Webcretaire]

Thanks Lep for the idea:

Right now we have detailed line graphs for each split, but for some reason we forgot to make one for the whole run. There are 2 ways we could add this:

• Add a new card before the splits detail, with full run infos
• Add a switch in options to make individual split graphs cumulated, so that they don't represent the time of this split alone, but the cumulated time so far (in which case the full run time corresponds to the last split time)

Second option would be way harder to program probably, but it would be more powerful because it would also allow people to see their best pace at any point in the run, which is nice. Maybe start with the first one and I'll think about the other one later
