DB/Quest: Flight of the Wintergarde Defender

1) Add missing Helpless Wintergarde Villagers and associated updates for these
2) Script quest, based on original work by @Rushor
3) Fixed credit for rescueing villagers as this did not work in original script and added wintergarde mine to areas where gryphon is allowed to be flown as the tooltip for the mount states thats its allowed there
