optimizations (php only)
- removed unnecessary call to array_unique in get_image_ids_for_tags
- put back in smarty exec time counting (debug mode) for each included template
- prefix some smarty modifiers with @ in some templates
- do not call format_date (still very slow due to mktime and date even after prev commit) from category_default.inc.php - if used in templates format_date can be used as a smarty modifier

- better template debugging tweak (the smarty console is shown only once at the end)
