Add callers to the pile-up when a QSO is done (F6FVY) (#261)

Add callers to the pile-up when a QSO is done #260
    
Formally, no caller was added to a QSO was done, and hitting F1 several
times in a row was adding too many callers regarding the activity
setting.
    
With this mod:
1. New callers may be added once a QSO is entered.
2. The total number of callers is always respecting the activity setting
