Othercontent would often contain the opening tag of the next heading /
section. By looking for the closest node with a previousSibling we can
more-reliably escape the heading.
Also, only add the initial placeholder if there's content before the
first heading. We do this by testing for any siblings before the
startContainer of the first heading -- if there are any, assume this
means there's some sort of content. (This can still result in a
placeholder with `othercontent:""` if there's only whitespace before
the first heading.)

name and id are supposed to never be null. Calling getName() or
getId() on this object would cause an exception.

Change the HeadingItem constructor to take a 'null' headingLevel
and store this internally with the constant. Change the JSON
serializer to convert this back to null.

Sequential numbers aren't great because they change when an earlier
comment is archived. Parent comment/heading IDs should change less
often.
This also makes much more sense for disambiguating subsections,
e.g. a dozen identical ===Votes=== sections for a dozen proposals.

Previously, only comments could have IDs, because we only needed IDs
for replying. But we might also use them for notifications soon.
