Adds partial support for PDF embeds.

Changelog excerpt:
- Added partial support for detecting objects and files embedded within pdf
  files (due to the nature of how this has been implemented, for the
  purpose of scanning these embedded objects and files, phpMussel will
  regard pdf as an archive format; this is intentional).
