textDocument/didOpen: index related files when a header is opened

Fix MaskRay#180

index.initialBlacklist: ["."] can inhibit initial indexing (useful for larger code bases).
Opened files are still indexed, though.
This heuristic allows related files (a/foo.c a/b/foo.cc) to be indexed when a header (foo.h) is opened.
