Title: Save number of lines for staff types

Number of lines in a staff type is written to score only when != 5. Different staff types have different defaults (tab has 6 lines as default). A TAB with 5 lines has its number of lines not saved.

This branch unconditionally saves the staff type number of lines to avoid this (bug report #17124)
