Merged from 1.9 and checked :: MDL-12221 :: I added changes to weblib and the forum and glossary view pages, the custom_corners and standard theme to get those pages working.

In the view pages I changed the container function call to a simple "echo 'div ...'" to avoid the custom_corners container overhead and page oddity.

In weblib I added "clearfix" handling to the function "print_box_start($classes ...". "clearfix" is handed over to the containing divs. This is a hack, but I didn't know how to handle it without rewriting too much areas.
