Pumpling v1.3.0

Added

• Group classes (#10): «Group class» in the start sheet – pilates, stretching, yoga, circuit, HIIT, tabata, dance, aqua aerobics, kickboxing, martial arts or anything else, with a name if you like. Only a timer runs; there's nothing to log as it goes. At the end you mark how hard it was (1–10), how it went and which muscles worked; exercises can still be logged with «Log exercises too». The pets eat by the minutes and the effort, the class counts for the week, the muscle map and recovery, and «Do it again» starts the same class.
