toc for user manual: Subsurface-mobile

[Willem Ferguson]

I notice the there is a table of contents heading but no table of 
contents in the user manual for Subsurface-mobile. My asciidoc command 
for creating the user manual is:

asciidoc -a toc -a toclevels=3 -a theme="compact_subsurface" -a 
themedir=$(pwd) -o mobile-manual.html mobile-manual.txt

This should include the javascript that creates the toc withinin the HTML.
Kind regards,
willem
