More auto newlines

[aunger]

Can the forcedNewLines flag be expanded (or another flag added) to add more newlines in USFM serialization?

The UBSICAP docs call for a linefeed before every paragraph marker, for instance.

Another place it would be helpful is at the end of \s section headers. If I programmatically add an \s node into the JSON tree, then I must take care to end it with a linefeed. Could USFM-JS handle this bookkeeping for me? Thank you.
