sw tooltip on bibliography fields: add the actual tooltip functionality

- Similar to e.g. SwMacroField::GetMacro(), add a new
SwAuthorityField::GetAuthority() that returns a string which is similar
to the one-liner text node in the bibliography table for a given
bibliography reference.

- Base this on the recently added
SwAuthorityFieldType::CreateTOXInternational() and
SwTOXAuthority::GetText() to share code with
sw::ToxTextGenerator::GenerateText() and SwTOXBaseSection::Update().

- Finally extend SwEditWin::RequestHelp() to actually provide the
tooltip on mouse hover.
