  - Added VFSClassLoader, and test cases.
  
  - API Changes:
      - FileObject.getContent() can now be called for folders.
      - Added FileObject.getParentLayer()
      - Added FileContent.getCertificates()
  
  - Implemented FileContent.getLastModifiedTime(), setLastModifiedTime(),
    getAttribute(), and setAttribute().
