fix fpm settings for session.auto_start (php_flag -> php_value), nginx poodle "fix", wheezy config for fpm with fpm vhost

-session.auto_start needs to be a php_value since it gets passed a 0 or 1... and not on/off which causes the fpm to not start at all.

-disable SSLv3 on nginx as well

-changed the config section to reflect the change on the fpm configuration which now needs to have the webserveruser inside the froxlor vhost group when froxlor vhost is enabled. since this isn't done automatically for manually added users

(tested on php 5.4.34/nginx/php-fpm)
