core (tools/common/template): helping methods/filters for templates: - Indexer class (used with next_gidx/cur_gidx) allows to get per page indexes, usefull to have unique id to reference - blog_date is a Q&D filter to get relative dates, should be replaced/improved in the future - ScriptsHandler (used with scripts_handler) is intended to be a way to add scripts from template, and group them at a specific location of the page. It is not used yet and may change heavily or disappear in the future.
