SimpleQuestTracker

All new sorting mechanism to avoid any interference from Carbine's Episodes sorting.

Removes out of zone quests when moving between zones.

Numbers quests in the same way as the original Carbine QuestTracker.  Note that even Carbine's own tracker doesn't always line up with the map and mini-map, and sometimes re-uses the same number twice on the tracker.  I have tried to make this mod clean house a little better, but there may still be issues stemming from trying to match Carbine's code.
