- images.file categories.permalink old_permalinks.permalink - become binary

- session security improvement: now the sessions are valid only for originating ip addr (with mask 255.255.0.0 to allow users behind load balancing proxies) -> stealing the session cookie is almost a non issue (with the exception of the 65536 machines in range)
- metadata sync from the sync button does not overwrite valid data with empty metadata
- other small fixes/enhancements:
 - added event get_category_image_orders
 - fix display issue with redirect.tpl (h1/h2 within h1)
 - fix known_script smarty function registration
 - query search form not submitted if q is empty
 - better admin css rules
 - some other minor changes (ws_core, rest_handler, functions_search...)
