* design based on Samuel's mockup + Hannah's adaptations
* on each plugin actions shown as buttons in a single column (better compatibility with verbose languages such as German)
* description always shown (no more need of the "show details" action)
* filter based on plugin title/description (javascript, no page reload)
* hide inactive plugins if they are 8 or more
* plugins no longer shown in the admin left menu, they instead get a "settings" action if relevant. Compatible with the old trigger get_admin_plugin_menu_links but new method is to simply add a "Has Setting : true" in the main.inc.php header
