Add Anchor to groups like Exported/Internal.

[peter1000]

this should not be too hard and one can link internally the Api-Index - also maybe helpful when style is not one of the h1-6.

I can do that later or tomorrow

If possible add an anchor to Exported/Internal, all groups of types even if they are not displayed. This would allow referencing it internally: These are also stable names and do not change.

Exception: one might get a dead link if some groups are filtered and skipped e.g.

a.md references in a docstring:

"""
[see section](#modulename_types)
"""

but in a custom saving one uses a setup without types.

save("docs/api/Lexicon.md", Lexicon; category_order = [:method, :macro]);

Gets also messy if a other module is referenced (which involves relative path) and that the saving path is changed.

Anyway might still be worthy at least in a forum one could post a link to a section in a nice way.

Adding permalinks to the section groups will show up in the side panel - not sure if one can do something about that without changing the mkdocs theme.

In the new Docile (julia 0.4/0.5) not anymore relevant.
