* glom/report_builder.[h|cc]:
* glom/xsl_utils.[h|cc]: Moved to:
* glom/libglom/report_builder.[h|cc]:
* glom/libglom/xsl_utils.[h|cc]:
* Makefile_glom.am, Makefile_libglom.am: Adapted, also adding a
-D define for libglom to access the xslt file, though I am not happy
about a library needing a file to be installed.
