new feature: meta tag for author info is available.

removed:
  parsers/DocumentName.java (MetaParser supersedes this Parser)
added:
  parsers/MetaParser.java (it looks for meta info and updates them to PresentFile)
modified:
  conversion/ConvertFile.java (now it initiates some of the PresentFile fields to null)
  parsers/Header.java (Meta field 'author' added)
  parsers/ParserList.java (added MetaParser, removed DocumentName)
  status/PresentFile.java (new field 'author')
  todo (update todo)
