Doxyfile.in: Remove obsolte doxygen tags from all our Doxyfile.in files.

Doygen tells us:
warning: Tag `SHOW_DIRECTORIES' at line 507 of file Doxyfile has become obsolete.
To avoid this warning please remove this line from your configuration file or upgrade it using "doxygen -u"
warning: Tag `HTML_ALIGN_MEMBERS' at line 879 of file Doxyfile has become obsolete.
To avoid this warning please remove this line from your configuration file or upgrade it using "doxygen -u"
warning: Tag `USE_INLINE_TREES' at line 1065 of file Doxyfile has become obsolete.
To avoid this warning please remove this line from your configuration file or upgrade it using "doxygen -u"

So we are nice and remove them. A yay for the day where we have amerged tree and
not two dozens of Doxyfile.in files floating around.
