Subject: fig, table-wrap & caption Divs for JATS writer

Support writing <fig> and <table-wrap> elements with <title> and
<caption> inside them by using Divs with class set to on of
fig, table-wrap or cation.  The title is included as a Heading
so the constraint on where Heading can occur is also relaxed.

Also leaves out empty alt attributes on links.
