* src/gdcmDocument.[h|cxx] : set the Transfert Syntax values to the header

   * src/gdcmDocument.[h|cxx] : set the Transfert Syntax values to the header
     file, to be accessed by other files (like gdcmFile). Remove commented
     code. Move the change of the header to the gdcmFile, using the
     DocEntryArchive
   * src/gdcmHeader.[h|cxx] : the write is completely made in the Header.
     To be sure of that (and simplify calls), the Write of the header now
     gets a file name and not a file pointer (std::ifstream).
   * src/gdcmFile.[h|cxx] : apply the write file type to the header, using the
     DocEntryArchive. Remove all open of the written file
