    Decide whether to send statistics to Esmska server or not. We don't want to send stats too often so that the server is not overloaded. The current decision algorithm:
    
    If this is the first time Esmska was ever started, don't send anything.
    
    If this is the first time Esmska was started in current month, always send.
    
    If today is 20th or earlier day in the current month, send stats at maximum once per 5 days (check last submission date and decide).
    
    If today is 21th or later day in the current month, send stats at maximum once per 3 days (check last submission date and decide).
    Returns:
    
    whether it is appropriate to send stats now or not
