Make "copy line breaks from full score" a parameter (checkbox) for generating parts

When generating parts, it could be very worthy to copy the original "line breaks" to the certain part.
It might be not useful when you decide to make a part that should be as reduced (in pages) as possible. (multiple rests, etc.)

BUT it could be very useful, when for example creating "lead sheets" and want a certain layout in any part/full score. (for example typical 4 bar realbook look-a-like)

An alternative could be a definitely more complex "intelligent rendering algorithm", that produces lead sheet like layout on its own. (For this one has to determine rules ... so it looks like in the new real books)
