Prepare QtHelp library for modularized documentation.

- Support ".." in QCH documentation file paths.
  This essentially means that we stop using cleanPath, and where needed,
  prepend the virtual folder name, followed by "/..", in front of the
  original path.
- Remove com.trolltech default DocPath since this was not used anymore.
