This commit implements the .tex-based online help system in LON-CAPA. It may be necessary to manually run loncom/build/help_graphics_converter.pl and doc/help/rebuildLabelHash.pl after a cvs update, and loncapa_apache.conf may need to be manually copied to /etc. (The loncapafiles.lpml has been updated.)
