[Ulf-D. Ehlert <ulfehlert src gnome org>]

commit 4b440a5158235c6718eaaac63f6b87a7b642fccd

    Enable to use floating images in HTML
    
    Add an XSL stylesheet that passes 'condition="float"' attributes
    of <inlinemediaobjects> or <mediaobjects> without <caption> as
    class attributes to HTML. Modify CSS stylesheets to make those
    images float.
