Fix member: queries for classes/structs that only contain member variables or member functions.

Previously the member: query would fail unless the class contained at least one variable and

Add files for test case.
Fix include links for filenames which are suffixes of other filenames.

Previously if bar.h and foo_bar.h both existed then #include "bar.h" would not be hyperlinked.
