Maps now save the spawn area ID, to have better control over which are
activated or not.
All maps refactored to have unique spawn area id. Spawn group now
defined in "spawngroup" property instead of name (id).
Populated most of the quest droplists (shop droplists still left to do).
Fixed issues with the Prim and Blackwater quests, that were never marked as completed under some circumstances in v0.6.9.
Moved tiles on a lot of maps to their correct layer (from "Objects" to "Above" for example)
Added deterministic sort order to quest list.
