   * Test/TestReadWriteReadCompare.cxx was properly written (with a call
     to gdcmFile::SetImageData()) BUT since gdcmFile is brain damaged (see
     new comments in this file) we temporarily (sigh) move to a weaker
     form of test...
   * Test/CmakeList.txt: with the change to Test/TestReadWriteReadCompare.cxx
     we don't need to black list the following images anymore:
      - 8BitsUncompressedColor.dcm
      - OT-PAL-8-face.dcm
      - US-PAL-8-10x-echo.dcm
   * src/gdcmDocument.[h|cxx]: RE-Reverting to version 1.42 with the proper
     fixes and the beautified code ;-)
     This fixes the bug introduced in version 1.42 (when beautifying)
     that made the parsing of 8BitsRunLengthColor.dcm unproper.
     Note: ctest was blind to this bug (this means we need to still
           improve the test suite). The bug could be detected by using
           gdcmbin/bin/PrintDocument $GDCM_DATA/8BitsRunLengthColor.dcm
           or by using
           gdcmbin/bin/ReadWrite $GDCM_DATA/8BitsRunLengthColor.dcm
           and by displaying the (garbage) produced file temp.XDCM...
