plugins only:

- fix in category_default.inc.php (action parameters were wrong if show_nb_comments was true)
- refactor actions and events in picture.php in order to give more flexibility to plugins
- added some variables in index.tpl (not used by pwg itself) to allow plugins to add their own content
