	Remove header and footer HTML fragments

	* docs/reference/libsigc_{header,footer}.html_fragment: Delete
	files.  These custom fragments were an unnecessary maintenance
	hassle.  Also, the files were out of date with respect to the
	encoding and CSS classes used by Doxygen.
	* docs/reference/Doxyfile.in (HTML_HEADER), (HTML_FOOTER): Set
	to the empty string.
	(PROJECT_NAME): Substitute @PACKAGE_NAME@.
	(PROJECT_NUMBER): Substitute @PACKAGE_VERSION@.  It does look
	nicer in the generated HTML pages, and is probably also less
	confusing.
	(SORT_GROUP_NAMES): Enable for predictability.
