Pierre Goiffon ecebe4ecd5 N°3416 XFrame and cache headers optimizations
* Remove XFrame header set in \WebPage::no_cache : not this method responsability, was confusing :/
* Remove no_cache() calls when already set in page constructor (ajax_page mainly)
* Also calls everywhere the \WebPage::no_cache method instead of setting headers manually
