Update for Doxygen 1.8.

* skeletonmm/doc/reference/Doxyfile.in: Update with Doxygen 1.8.3.
doxygen -s -u Doxyfile.in
* util/post-process.pl: Don't collapse almost all multiple spaces to a
single space. It distorts the formatting of @code blocks, even more so with
Doxygen 1.8.
* util/doxygen.css: Add rules for div.fragment and div.line. Used for @code
blocks by Doxygen 1.8.
