1.) fix failing compilation of ommysql plugin
    (s/ommysql-config.h/config.h/)
2.) fix mysql configure check (although the default is no, we did check for
    the mysql devel files)
3.) Create a separate Makefile.am for the doc files. This cleans up the
    toplevel Makefile.am considerably and makes it much more readable and
    maintainable.
3b) Assign the html doc files to html_DATA. This means, they are installed
    to $(hmtdir), which by autoconf standards is
    $(prefix)/share/doc/$packagename/.
4.) Reformat the SOURCES line to make it better readable and maintainable.
