tools (common/template), jp: refactoring to handle multiple sites: - site can now be specified in template header before theme, for instance: (some_site/some_theme)path/to/template.ext - absolute template paths are now implemented, but Renderer must be instanciated with trusted to True for security reason (it's the case for jp) - a new "front_url_filter" callable can be given to Renderer, which will convert template path to URL seen by end-user (default to real path). - the "front_url_filter" can be used in templates with… "front_url" filter - template_data is a new named tuple available in templates, which give site, theme and template relative URL - search order is site/theme, site/default_theme, and default/default_theme where default link to sat_pubsub templates - when loading CSS files, files with _noscript suffixes are now loaded, and used when javascript is not available - "styles_extra.css" is also loaded before "styles.css", useful when a theme want to reuse default style, and just override some rules - new site can be specified in sat.conf [DEFAULT] section, using sites_path_public_dict or sites_path_private_dict (where sites_path_private_dict won't be used in public frontends, like Libervia) - "private" argument of Renderer tells the renderer to load private sites or not - templates are now loaded from "templates" subdirectory, to differenciate them from other data like i18n - jp template output has been updated to handle those changes, and to manage absolute templates
