pages, tasks (brython): use set for scripts + common template data: - scripts are put in a set using a namedtuple, this way duplicates can be avoided easily - if `template` is set in dyn_data_common, items there are set in template data if they don't already exist - (brython): common template data is used to set body_onload when there is a root brython script and no page script
