Provide option of filling measures with rests with or without augmentation dots

#4867: Rests in measures should be grouped according to time signature was resolved and the result is mostly good, but it would be nice to have an option to decide whether rests with augmentation dots are allowed. For example when you enter an 8th note in a 6/8 measure, the rests automatically generated are two 8th rests, one quarter rest and one 8th rest if the option is off, or two 8th rests and one dotted quarter rest if the option is on.
