* configure.in: added 'gtop_guile_found', 'gtop_want_names',
'gtop_want_guile_names' and 'gtop_want_examples' for use in
'gtopConf.sh.in'; added 'include' and 'include/glibtop' subdirs.
* configure.in: 'GTOP_INCS' and 'GTOP_LIBS' now really
point to the places where everything gets installed and
no longer to the build directory, so that they can be
used in 'gtopConf.sh'.
