Fixed issue #07895: Quota are not tested for hidden question (relevance to 1)
Fixed issue : Previous button in quota in citronade are not the same.
Dev: Change sentence of quota_action : reflect reality now
Dev: Don't change behaviour for quota_action=='2'
Dev: remove some $_POST var ($fieldname not in actual page)
Dev: this fieldname is needed for EM javascript : put disabled='disabled' inside.
Dev: DON'T do same think for relevance : else eremoved $_POST[$fieldname] : to be fixed
Dev: Same HTML previous button for quota page: todo : add navigator.pstpl (but allow save and clear all must be removed)
