The new offline template for Qt 5.6, including simplified CSS rules
suitable for rendering with a QTextBrowser, requires the navigation
bar to be generated as an HTML table instead of the previously-used
unordered list.
Make QDoc select between the two based on the contents of
HTML.postheader .qdocconf variable, which defines the header of
the navigation bar.
Modify the old offline CSS to look good also when the nav. bar
is a table.
