Merge branch 'fix_print_css' into 'master'

change the default media type to all so that printing is improved ref #127

setting the default media type means that css files get loaded on printing, specific @media changes might be worth doing to improve the printing layout but CSS files  should be loaded by default unless they are explicitly not for a particular media type.
