Add a newline between objective sections

This is set up that there will be no newlines at the end of any section, unless you have
only a summary key, which no one would do. However, there will be a newline at the top of
the dialog if you don't have a win objective, but no one would do that either.

Note that because of newlines not showing up properly on Windows, this won't be viable
on that platform.
