Instead of just [[section]] you can have [[section][name]] and
depending on format the name will be displayed instead of or
in addition to the section number referred to.
Not sure how useful it is since you can always force one section to have the
max number you want instead.
Anyway also added filling up with dummy sections to make shuffled numbers
on sections in the correct range from 1 to max.
Switched to text mark-up even more similar to org-mode, also more
similar to typical wiki mark-up, removing python-style format from
sections (but not from the templates).
