guest_view.t; minor tt print_view bugfixes

patched pdf rendering to work on deployment server as well as dev localhost; factored out some of print_view.tt into separate snippets

updated bootstrap to 2.3.2; commented @media print * { } declarations in boostrap.css to prevent loss of colours in printed html; removed min.css so don't have to manually edit 2 versions every update; print_view works with mail_reports.pl

adapted print_view for print run - need to fix loss of text colour in print_run-generated reports when printed
