TOC problems

[pmudry]

If the table of figures or other tables are empty, the title is generated nonetheless. Either let the user choose what to include or remove the header if not present (for instance, the problem was present in the SOS invader report).

Should it simply be a with-outline boolean ?
It leaves the user free to add the outline how they like it, or not at all
There could also be multiple parameters, one for each type of outline, like @tschinz did here
