Fix unpack error when the doc has no toctree

As stated in issue #17, when a doc without a toctree (single page/all
pages are orphans), the doc build would throw an exception because the
wrong value (an empty string) would be returned by the navigation_tree
method.

Resolve git directive link with tree, bump version

"blob" path does not work for compound branch names at the root path,

Simplify filtered tree logic, bump version

Always hide other toctrees when on a page included on a toctree.
Do not rely on doctools lut.py anymore, since was confusing having to
update it to affect other repository.
The "topic" entry on the lut.py is now the path to the index.rst page
of the toctree, generally an orphan page, to reduce nesting by one level.
