doc: make doxygen.cfg.in work with doxygen 1.6.1

* DETAILS_AT_TOP is deprecated and newer versions of
  doxygens are warning about this. Remove this option.
* Empty HTML_HEADER as newer versions of doxygen check
  if the file exists and fail if it doesn't. Looking at
  the history of this project the file never existed.
* This continues to work with doxygen 1.5.6.
