Pumpling v1.2.0

• How to do each exercise: every one of the 275 has a short description of the technique, on its page and on its card.
• Edit a past workout: change sets and exercises, the name, the note, the day, the start and how long it took. Records are worked out again; what the pets ate stays.
• Left and right apart: one-arm and one-leg exercises can be logged as L/R pairs; the next time and routines keep the pairs.
• Recovery on the gym screen shows resting and ready muscles together on one figure, with both lists under it.
• Fixed: «How to log it» gave pull-ups as the example for every bodyweight exercise; now the example names the exercise itself.
