Ramjet Memorial Challenge

[Dirk Broer]

Please check the BOINCstats challenges to confirm I set up the Ramjet Memorial Challenge 2019 correctly.

Not only at BOINCstats, but also at WCG, twice
Perhaps we ought to change one of the WCG challenges into 'Points' or 'Results Returned'. Someting fishy at WCG challenges though: you can't select our challenges here
