LibManual: Associate SubsectionNode with similarly named markdown file

Browse source 
For a subsection named `Foo` with a markdown file `Foo.md` in the same
directory, the document `Foo.md` will be returned when the subsection is
selected.

This prevents PageNodes and SubsectionNodes from sharing the same
name, which fixes an issue in Help where subsections could not be
navigated.
