- Fixed some call-time-pass-by-reference warnings. - Allow a new tag "div" , on which effect=slide works as well. - Changed how body tags are added, so that we can pick a CSS class for the body tag dependent on the template. - Changed some of the ways on how slide XML is opened, related to incomplete PHP 6 implementations of functions. #- Rasmus, I tested those changes with a few of your talks as well, they look # fine here, but you might want to double check.
